You can watch a Youtube video that will tell you how to fix your car engine, and then try to do it yourself.  You can read a book that will tell you how to plug a hole in your roof, and then try to do it yourself.  As long as you are not worried about your car breaking down in the middle of nowhere, or your roof leaking on a raining night, you will be fine.

The same principle applies when it comes to creating your own business or LLC, or hiring a lawyer to do it for you.  When you go with an attorney you gain peace of mind.  The job will be done right.  Talking to your attorney will help you determine what structure is best for your business, and most importantly an attorney will help you create a flexible operating agreement that will fit your individual needs. Your attorney will answer your specific questions, and guide you in the process of growing your business.  As years go by, your attorney will help you create a structure that will enable you to hire employees or take on partners.

Do it yourself websites and books offer you standard language and standard contracts.  These contracts may serve you well, and you may never have a problem.  However, just like the broken car engine or the hole in the roof, you could be in major trouble at some point in the future.  You have nothing to lose by talking to an attorney about your new business.  Most will offer you a complimentary consultation.  At the end of the day, the decision is yours, and just like the hole in the roof and the broken car engine.
