I'm going to list my methods on this and it might be a bit of a lengthly post but YODO.
Farming - Honestly, just do this with everything. Whatever you do you can't just "No life" it you need a little bit of a break before you end up just getting tired of it completely. You need to take regular breaks and farming helps you do just that!.
Assuming 1 farming this is what I recommend.
Level 1. Make Supercompost, utilize Canifis/Fally/Seers/Ardougne for this and you will level up quick. Combine this with Guams later on and then Oak trees and you will get 32 very soon. Also begin planting Limpwurt roots/Strawberries when you can.
At level 32 begin farming ranarrs (Get Magic Secaturs) combine with Limpwurt roots (2k each, 3 per patch and making a tidy 5k profit on the seed. You can make Super Strength potions with these to train herblore and make money or just sell them off.) Also farm strawberry seeds for more exp and then I like to put them into baskets and use them as food (25hp per) it's quite expensive at 600 ea per seed and 3 seeds per patch but if you're using it as food + getting exp it's worth it IMO. Swap it up to Snapdragon seeds when they're readily available for more profit. Toadflax seeds provide great profit Herb > seed but still nothing compared to ranarr or snapdragons.
A side note; fertile soil can be used from lunar spellbook if you desire for super compost effect.
Now, that's just a supplementary money making method but I also recommend.
Air Orbs. Unpowered orbs @ 76ea + Cosmics @ 140ea x3 = 496GP. Air orbs instantly sell at 1300 ea but you can get 1350-1360 for them. Each trip is 3 minutes and you can wear graceful in a bot world for added protection if you desire (I do). This is a 461,160 profit margin if you complete each trip in 3 minutes, the method is semi AFK so you may well take advantage of that and maybe you won't make quite as much but combined with farming you should still rake in 500k+ an hour easily. The magic experience is also a nice bonus
Black Chinchompas. This is a great way to make cash but is very interuptable, imp boxes are a must here. You can see pkers from the top of the hill first, however a slight lapse in concentration or AFKing can be the difference between life and death and maybe a couple hundred chins as well. Zulrah's ranged defense being buffed has caused a decline in the item but if you can do this with 6 traps and no major interruptions you can still rake in 500k P/hr which may go up to 600k P/hr combined with farm runs. Be warned though, this is much more click intensive than Air Orbs.
Red Chinchompas. Like Black Chinchompas at less profit but less deadly. I know there are plenty of bots but you can utilize the bot worlds for this, you may struggle for a world but if you get in there you may still be able to pick up 350k-400k an hour!
Karambwams. These are great profit and pkers are always in demand for them. Last time I checked I was making 600gp on a karambwam EACH. I tend to afk cook these at burthorpe and make about 20m profit before it gets tedious. Most people don't bother cooking these due to the Tai Bao Wanna trio quest requirement and need for cooking gauntlets but there is nothing that yields a better profit on your way to 99 cooking.
320gp profit per fish and I believe you can max at a 1300 cook per hour at burthorpe but let's say 1100 as we probably will utilize the AFK that the cooking skill provides. 352k per hour, hardly click intensive and an easy skillcape. Over 400k an hour with farming! This is a much better money maker method than fishing is.
Zulrah: RNG based but there are so many good drops you really can't go wrong. Give it a go, I can't delve into this too much as I haven't been yet but we've all seen the results. Money p/hr is N/A here
Barrows: Great chance of items and if you're using a trident you might make profit on the junk runes and racks. I will say that you should get 13 KC and do those elites as soon as you get them though, that fury ornament kit is almost as expensive as a guthans spear and you're just as likely to get it. Per hourly rate is N/A here as well.
Runecrafting: Invest money into lava runes and make them until 82 for double astrals. You can make about 5,000 astrals an hour and at the current market price that's 500k an hour. This doesn't sound too great considering the money you invest but nature runes are a 1.1m an hour item! If you do astrals from 82-91 you will die of boredom yes, but you will never have money problems ever again.
Sara GWD: Soloable or with a team you can make great profit. ACB's and Sara hilts really pay off, I've had two sara hilts on solo's and although it will take a lot of time and you will wanna kill yourself you just need that one drop to make it all worth it.
DKS: Probably one of the steadiest PvM monsters at hand, I like to kill Prime and Rex when I'm on my own. Some trips you'll profit, some trips you won't but most of the time you will make some money. On a tank with Guthans and SGS I tend to make about 1m an hour if my luck is semi-decent. It CAN be higher but it can also be lower too so bare that in mind. You will also have to pay for things like trident charges and damage to barrows armour but overall, I think DKs is a great money making method, however I tend not to go with team mates as I seem to make slightly less then.
