There are websites that will do it. My state even has a website where you can register with a credit card in about 5 minutes. Doing that first step by yourself is fine. I had my lawyer do it and I found out that all they do is have a paralegal go to the website. However if you have more than one founder you'll want to go to an attorney and work up some sort of agreement among the founders. Right of first refusal to sell their share, what happens to a founder's shares if he prematurely meets his demise, what happens to a founder's shares if he gets divorced, etc. There are a whole bunch of these situations to consider and you need to get the answers in an agreement up front.
