Anyone know a place that can teach me to create custom roms?

I want to make my own custom rom for my sgs3 i747. I cant find any place to help me out with it. Where should I look? What programs will i need? etc...

This might be a good place to start:
[GUIDE] [how to] CREATE OWN ROM [FOR ANY ANDROID DEVICE] [FOR N00B] [EASIEST METHODS] - xda-developers

I'd suggest hitting the AT&T Galaxy S3 forum on xda. There are a ton of developers there working on roms. You might be able to join a team on a big rom or find someone who can guide you in the process of making your own.

Good luck!
