Freelance classical animation rates

Hi, I was wondering if anyone could help me get an idea of what I should charge for a particular piece of animation a client wants to commision. They want me to take a previously designed character who is a realistic human figure, slightly anime-esque (meaning theres tassles on his wrists, so lots of overlapping action, fair bit of line mileage), and animate him hitting a drum he has at waist level, its like a bongo perpindicular to the floor. This will probably be done to a prerecorded piece of drumming, not something that can be a cycle. It'll probably be 2-3 seconds (?) of full anim, so at least 40-ish drawings. Any suggestions would be greatly appreciated, thanks!
