Hi,
I am a highly experienced 3d artist and mechanical engineer. I have done alot of product development projects as well as product renders, including for wed based interactive turntables, and am sure i can do a great job of yours.
I have had a look through your document, and believe what you require is easily achievable.
please have a look at my portfolio, where you will find examples of my work as well as my resume. If there is any more information I can supply, please don't hesitate to ask.
Regards
Matt
