My usual rate is 15$ hour, feel free to ask for a quote as time will vary project to project.
Rough estimates (USD):
Character illustration - 30-100$
Full CG illustration - 75-300$
(Ranges depend a lot on detail, style, number of characters, background, etc.)
I accept Paypal payment.
Primarily use email, but happy to accommodate with Skype, Discord, etc.
Let me know what works for you, and I'll see if I have it!
