I have some experience in AutoCAD and engineering animation with Solidworks/Inventor as well as Anim8or, Maya, and Blender. However, can you tell us more about your design and patent information, I'm having a hard time finding your patent at USPTO. Also, to what extent is this animation? I've spent a year working on a "simple" animation before I felt it was good enough. Also, paying handsomely can have varying meanings. If you were to go to a professional and ask the same question, he would probably quote you from $10-30/hour. I know from experience that animations always take longer than you would like. So for example; I could charge $10/hour at 6 hours a day for 1 month, it would cost you about $2000.
So consider and answer these questions:
-Who are you? (If anyone takes you up on this offer, they need to know their employer.)
-What is your design?
-What does it do better than the competition?
-Do your diagrams include a 2D/3D CAD model?
-What kind of animation do you want? (describe purpose, parts breakdown, show internal operation, etc.)
-How advanced do you want the animation? (throw in some exploding cars, photo-realistic rendering, extreme modeling accuracy, or combustion in the cylinders, audio, music, etc.)
-How much are you willing to pay for this animation even if your product does not sell? (fact of life; many patents aren't built or sold)
-How much are you willing to pay if it does sell?
-Do you have any questions for me?
I know, it's a lot to answer but necessary if I'm to consider helping you out.
Thanks,
ADSohr.
