Marketing tips for a business I am about to launch.

Hello everyone, I just signed up to this forum today and have read a lot of good quality info!

I am not sure what I am allowed or not allowed to post in here, so I hope this is ok.

I am starting a peer to peer massage business, starting locally (USA) possibly only California first.

I have the pre launch almost complete, meaning, people can pre sign up and refer other people and make money from doing this. I believe this will help create a customer base rapidly.

I have joined a ton of massage groups on facebook, I have looked at a ton of massage therapists on craigslist. I have researched different job boards for massage therapists.

I need customers and I need massage therapists. The pre launch has a signup for massage therapists so I can start getting massage therapists before my site goes live.

My question is what is the best way to drive traffic to my site?

I don't want to do anything illegal.

From doing a ton of research, Airbnb started off by replying to craigslist ads under short term rentals. This is genious and from what I can see illegal.

I could easily email or even txt massage therapists and ask them if they heard of blank.com. Or even better, let them know I want a massage but would like to compete the transaction on blank.com website.

I believe this would get targeted massage therapists immediately. Though possibly not legal?

I am willing to hire a professional to get my name out as well, money isn't really the issue. Wasted money is a huge issue though.

Any thoughts or advice would be greatly appreciated.
