Hey guys I could really use some advice!

I've come up with this really great idea for a cell phone case and I really think it could be great so I've decided to get into the game. I'm a young college student and at this point it seems better to be creating something then trying to find a job. I'm relatively new to this trade so I was wondering if I could get some pointers, right now I'm working on a prototype for a patent, but after that is done I'm a little lost!

So here it goes, is it best to start up your own factory here or to outsource?
I know that companies like Incase have a factory in China and in the US, but as a start up which would be best? Would it be possible to find a reputable manufacture that wouldn't pirate my product?

I know I sound naive, but I feel like with proper marketing my idea could be huge which I'm good at (everyone says that I know), but as far as the manufacturing of the product I'm lost! Any advice you guys have I would really appreciate!!
