How to promote a start-up business for real estate virtual tours
I am a startup business for real estate virtual tours. I have a pretty competitive product and can upload to mls, create its own website, YouTube channel, hot spots, sign-up sheet and much more. BUT, I need some photo opps to build my portfolio, AND THEN I'm looking to market myself.
I don't know the first step. HELP!
