Look at sites like NOLO.com, Legalzoom.com and Intuit.com and follow the incorporation (LLC) links. Obviously they are in the business to sell you something, but they do a pretty good job of explaining the pros and cons of incorporating vs staying a proprietorship.
For various fees, these companies will complete your forms and file them with the state and provide your needed documentation.
In addition to any fees they charge, there will be a fee paid to the state for incorporation (in Georgia, it's $100).
