I had a girl from my local trade group do mine. Just go to Facebook and register a new account. Call yourself Somewhere' Windowcleaner. Use a new email account not a personal one. Just like joining this site. Add a few bits of info and you're done. New Facebook account set uP, join any local groups and 'add friend' to all the housewifes.
Housewifes choose window cleaners 90% of the time.
Then just post updates from time to time to let peoPle know where you are working the following week and see the enquiries grow. Absolutely great for feedback too. All their friends get to hear about you into the deal.
