Hi Sarah
(Marketing gurus? what do they know!

)
Here's a really EASY, EFFICIENT and FREE way of building a client base in your local area. Three words not normally seen in the same sentence.
Contact your
local branch of the W.I. and offer to go to one of their meetings and do a half-hour presentation on NLP, with a question and answer session at the end. The W.I. just love to get interesting people to come and talk to them about stuff. You do it for free, but you will get a cup of tea and a slice of cake.
Then do the same thing for as many more groups as you can, such as the Lions, Rotarians, Association of small-business owners, etc.
This has dual benefits. Not only are you establishing yourself locally as an 'expert' but you also improve your public speaking skills.
Regards
John
