I have done consulting in another field. Start with a client. Send an invoice. Cash the check. Then you have started a business. Everything else doesn’t matter (notice I didn’t mention doing any work, making a website, designing business cards, etc). Your social and business networks are the key to success. You can hire technical skill. Your job is sales. Good luck.
