I think I'd go for Cinema 4D. I just got a Lynda.com account and they have a bunch of stuff on it. I also have inventions that i wanted to create/patent so I think this is going to be a rewarding journey for me. Wish me luck. Thanks for the help everyone.
Oy. That's not the wisest choice.
While there's nothing wrong with buying Cinema 4D, I wouldn't recommend having to learn a new program and get the job done well, on time and on budget. You are bound to spend waaay more time on this ... and as they say, time is money.
Best of luck though. I think you'll need it.
