$10 per page? Are you expecting a page an hour? Because anything less and you'd be paying less than minimum wage.
Change that to $10 an hour and I might consider it halfway reasonable. That would be about $20 a page assuming the artist isn't also writing everything because you haven't even told us if you have a story written in the first place. What are you planning on doing with the finished product? If you are monetizing it then shouldn't the artist have a cut for doing half of the conceptualizing (the visual part) and all of the dirty work?
I'd suggest changing tactics by starting your pitch with what the project entails and trying to get artists interested in it instead of just saying "I have money and I am willing to pay you a small amount for your work". Otherwise you will get people throwing stick figures at you and quitting when you don't pay.
