Justin, you can become certified by filling out information on the internet. But becoming an LLC is not cheap.
I just went to this site:

and put in Texas (where you are from) and it's going to cost you almost $500 to become an LLC.
My advice...Use caution, write up a business plan, and put some serious thought into what you are doing.
