3D Modelling/Sculpting of cartoon character

I'm looking for 3D sculptor/modelling for helping me to create a puppet prototype for a project. Artist must strong skills with software like ZBrush, Mudbox, 3dMax and be creative enough to model character in a cartoonish/caricture style similar to [login to view URL] ZBush is prefered as 3D tool but not a must. The model wil later printed with a 3D printer, so artist should be familar with 3D Printing and exporting to STL files. I need a complete model, as well as all elements from the model, like head, hands, feet as separated models, so i can print the head for example without the body. Artist has to deliver printable STL files, as well the native fileformat of the used 3D Software, so i can improve the model later myself. As this is just a prototype there might be more similar work in the future, if every thing goes fine with the prototype of the puppet. Please to a bid with links to reference work as well information on the 3D software you want to use.
