Puzzle maker (photoshop)

I need an image designer who is very creative and has the ability to make 6 types of puzzles. I need 150 fun and challening puzzles of each of the 6 types. I have uploaded a demo on GAF. Knowlege of image file manipulation is required, preferrably in Photoshop, to make the puzzles. I can send you sample problems for each type of puzzle to give you some ideas. The last 3 pages of the PDF file I uploaded will require explanations, that is, by using 3d. Programs like eDrawings 2005 can do this very easily or if you are familar with another program like Flash, it may help too. I will pay 10% upfront. And you will get 15% upon completion of each type of puzzle.
