Suggestions? I would prefer a fun, enjoyable thing instead of a tedious skilling task
You've got a really nice account. Considering you're 92 range, why not go for 99 while making money? Try avansies, it's really easy and you can make over 400k/hr! You can get 99 range here easily, a lot of people do. Plus who doesn't want another skill cape?
You've also got a pretty high woodcutting level. Chop some magics. It's slow but it's really good money, even if you bot it.
You're also 72 slayer.. You're not far of from 85 and it'll require some work but once you can hunt dark beasts you can make good money from dark bows.
An alternative not requiring skills is getting white berrys. These spawn fairly quickly and they're good money. Try out my ideas!
The slayer and mining are low and don't matter anyway.

I might try get some extra cash on the account so I can make more from selling it. Any ideas? (It's F2P)
You've got a great account. If i were you i'd go to avansies like i said to Unique God. You could become a really good range tank plus make alot of money.
You've got 4 99's... GO FISH! You have 99! Just because you have the cape doesn't mean you're done! Raw sharks sell for over 1k each.. So in a day you can make 2m+ if you fish enough.
93 Hunter?! You can make MILLIONS if you keep hunting. Go for 99 and you'll make almost 10m from where you are now to 99.
If you need a P2P pin come talk to me.
This is my old account, i tend to play on my void pure now but that's just because this account got hacked and now all i have is 300k and i could never be bothered getting back all my stuff.
My idea for your account would be to start woodcutting yews. Cut about 2k so you have 900k+300k that you already had. I'd buy supplies and go hunt avansies. You have 75 range now and that's pretty good. Hunting avansies makes over 400k/hr so within a week you'll have millions, plus be 80+ range easily! Why not work on both skills at once?
You can also fish. With 65 fishing, you can easily fish about 1k lobsters in 2-3 hours. That's pretty good considering raw lobsters right now are at an all time high of about 450 each.
