LLCs do help seperate your personal assets from your business assets. If you wreck a car or burn down someone's house and your insurance isn't enough, then you don't want them coming after your personal assets. An LLC helps keep your home seperate from your business. I lease myself my vehicle, garage space, office, everything. The only thing the business owns are the products and tools of the trade.
Here is my favorite resource for this kind of stuff. As a paralegal I reference nolo all the time. They have some of the best books on this kind of stuff. Most of what I do is in intellectual property, trademarks, and patents, but this kind of information still comes in handy.
Barnes and Noble should come in handy if you are looking for a good book. There are many "LLC in a box" type things out there that give you all the forms and everything you need. They supply everything you need on a disc and explain how taxes and that stuff works. I've got a couple of them. When I started my business I bought "The Complete Limited Liability Comapny Kit" by Mark Warda. It is published by Sphinx Publishing and was the most complete resource I found. I also bought "Accounting for Dummies" which helps with the tax part of the business. Those are two resources I can definitely recommend. I paid $25 for the first one and $20 for the second one. That is much cheaper than a lawyer.
There are offices like
We The People :: Main page that would be able to help prepare your business without the cost of attorneys. I actually interviewed with them a year or so ago for a director of training position. They have a really smooth operation and it would be someplace that I would suggest for people wanting to avoid the cost of attorneys for things that don't really require them. I wasn't in a position to accept the job offer at the time, but I still keep in touch with them for future opportunites. That would still be my dream job I think...
Bottom line is that if you are going to start a business then it should start with forming the structure. Once you have formed your LLC and your business name is registered with the state and your business license is secured, then you can look into liability insurance and all that fun stuff. It is best to start out with a real legal entity first so that you can legitimize your business. You'll get a lot more business when you have the LLC behind your name and it is obvious you aren't some 16 year old detailing out of the back of his Mom's station wagon. :bigups
