I'd be happy to help you for a reasonable price. Right now I charge $5 per square (70x70 Roll20 square) for a custom token, so a 4x4 square huge monster would be $20 but like, a single medium sized character for your use in VTT would be just $5. You can privately message me to discuss further if you want, or keep looking. Don't go to Fiverr. They're a trash marketplace that exploits and extorts artists, lies to clients with a misleading price model, that attracts the lowest of the low quality newbies. You might get great art. You might get no art. You might get unusable art. You will almost always get a better result artistically if you just approach an artist whose art you like. Unfortunately Roll20's marketplace doesn't have any way to sell custom art, but most token artists here would likely consider a custom commission if you want it to match your game style. Or just browse DeviantArt for a bit and pick someone whose art you like. It's easy to get custom art if you're willing to pay! Good luck.
