At least in Indiana, starting an LLC takes about 15 minutes online, filling out a form. Then you go to the IRS web site and get a tax id for the new LLC. Then a business account at any bank, under the LLC's tax id. This can all be done in 1 day. I'm not intending to be critical, but rather pointing out that you don't need to pay a lawyer or accountant to incorporate.
The key thing after that is to separate your income and expenses into personal and company. Never mix funds. Get a separate company credit card. You'll probably have to start out using the LLC's bank debit card - that's fine.
