I love these stories. The timeline is precious. And the comments from folks saying "gee, you picked the most complicated business entity, joke's on you!"
Just looking at my own state (Michigan) I can form the most "complicated" entity for $60 filing fee. Using a fill-in-the-blank form online. And have it approved the same day for an additional $50. Get an EIN online from the IRS in 10 minutes. Walk to a bank and open an account in about another hour. Annual renewal fee is $20.
In less than a day and for $110, I have a corporation, EIN (federal tax registration number), and bank account. Open for business. An LLC is the same, just a different form filed with the state.
I can then open credit card accounts online in the business name, register for sales tax online (get the license in about a week), and open a stripe account.
Oh, and a businessowners general liability insurance policy is costing me $205 per year. $1 million in liability coverage.
