Create graphics with animation

Hi, I am developing a JavaScript game to be played on tablets. I am looking to create a brand, but initially I would like to have quotes for creating approx. 40 unique designs for animated rocks (yes I mean rocks! :). Please use your design flair to make them hilarious (to children) - they can have eyes, mouths, hair, glasses, arms legs etc, and should be 2D but with shading etc, made to look 3D so they stand out. Also they should scale nicely to fit within an 80px square. My children have come up with the following names for inspiration: Hard Rock, Baby Rock, Rock Muffin, Fuzzy Rock, Rock Star, Raster Rock, Scary Rock, Sad Rock, Happy Rock, Rapper Rock, Cheeky Rock, Geeky Rock, Jazzy Rock, Hairy Rock, Sporty Rock, Roly Rock, Rocky, Tina Rock, Kitten Rock, Pumpkin Rock, Sparkles Rock, Rosie Rock. Basically the funnier the better! I would like the rocks to have limited animation (blinking, tongues poking out, smiling, grimacing, raspberries etc.), so would also like sprite sheets to be created so they can be animated using CreateJS. Any questions please give me a shout. Many thanks and look forward to working with you!
