I'm exactly in the same boat as you, I'm renting rooms above a hairdressers and opening on Nov 1st.
So far I have been over there for a day to get a feel for the place, see how noisy it is, etc, and gave all the hairdressers a free mini treatment.
I have put a few posters up around the village, got the drums working by telling a few people I know in the village to start spreading the word.
I'm having an open evening on Nov 1st for an hour and a half where people can come upstairs to meet me, book appointments, have a glass of wine and chat about the treatments. going to have a balloon raffle and give out info bags with leaflets, money off voucher some chocs and herbal teabags.
I have offered 15 goodie bags to the first 15 clients to book an appointment.
For Nov I am offering a 40 min Reiki treatment for £15 normal price £25 for 55 minutes.
Have 200 postcards to hand out next week with all of these details on.
At moment I am 300 miles away on holiday trying not to obsess about it!!!
