Market Researcher

I am looking for a market researcher to phone all the coaches in the Winchester and surrounding area to find out what they offer, their USP, how they market themselves, their rates, packages and how many clients they coach in a week etc. I think we are possibly looking at 30 coaches in total more along the line of Life coches, small business coaches and NLP practitioners. There is no real time limit for this job but would like it done asap. Please quote for the job as a whole not on an hourly basis and highlight any information that I might have missed in order for me to work out how big the market is.
