I have commisioned several of our residents to paint some of my models, as have others here.

I have a warmachine caster painted by Mike travis, cost me 60 bucks and took him about 2-3 weeks.
I also have had about 1800 points of my Dark Eldar done up by Thomas(goatboy) for about 300. Whole army was done to a good table top standard in about a month.

It depends on what you want painted, how good and how fast. I think you will find someone easily enough but you will get either good speed or good quality, not both.

Hell even Spines paints real good but he is slower than....well nothing is slower than he is!
