There are some questions and reflections for you:

1 You cant actually start a business based on an area you know little about... well actually you could, but you shouldnt...

2 what product have you in mind to offer?... exactly.

3 what kind of contacts you have in the industry? (ie to who are you going to sell it, and who are you going to hire to do it?)

And money... about money i have to say that if i had the kind of money that starting a 3d bussines requires, i would probably just keep it to myself... and quit working... ever again...
