Hi, I've just spotted this one and thought I would get my bid in before you became inundated by suppliers from Delhi who can do the job for five dollars.
I'm a Game Developer by trade, but I spend 90% of my working day creating 3D animations, so it's definitely relevant to my workflow.
It would be nice to see your cad drawings, to get a feel for the project... I would also like to clarify, what kind of output you're looking for, ie; 'Photorealistic-boutique', 'Broadcast quality', 'for web distribution' etc etc.
I'm a UK provider and I'm happy to talk on Skype, if you'd like to discuss what you need in a little more detail.
I've been in the 3D/interactive sector for nearly 17 years, so I'm no spring chicken, but I know what a job costs and I don't make promises that I can't fulfil...
I'll leave it there for now, but if you have any questions, or would like to talk further, please don't hesitate to get back in touch.
Best regards
Mark
