Hate to rain on your parade, but you are a bit late to the party. Before you waste money forming an LLC, make sure there really is a profitable business opportunity for a UAS business focusing on real estate and videography in your local area. Highly unlikely. It has been a race to the bottom. There is no money to be made anymore. Real estate agents are notoriously cheap and minimize all their out of pocket expenses on listings. Most of them are now taking their own drone photos and videos. Most are also using their own cell phones for still photos. There are exceptions at the very high end of the market, but unless you already have connections and a viable source of referrals, you will be doomed to failure. No amount of marketing and sales online can overcome the perceived free value of your offerings.
