You don't need anyone to fit it for you. I was shopping around also for a while and ended up giving it a go myself (and thank god I did as it is so easy and saves you a good bit of money).
I see webcars is closing down and he offers prices fitted, but than he states that he no longer provides a fitting service. You can probably get the hood for a very good price from him. Ask him for the brand.
I fitted 2 mohair ones. Bought them from MX5 parts
Let me know where abouts you are in the country and I'll see if I can give you a hand fitting... (takes about 4-5 hrs in dry conditions and is really easy - and that's from someone who is very far from being a mechanic)
First I fitted this (geniune Mazda) in August 2008

Than, early Feb 09 my car was broken into and they cut the roof open. I ended up buying this and it's even better than the original Mazda one from above.

Just read the reviews. PS I am Robin van de Ven
I started an online manual when I fitted the one in August, but taking all the photos was keeping me up a lot, so I skipped numerous steps with the photos. See here:

The roof has to 'set' for a few weeks as it is fabric you're working with, after that it is all smooooooth.
Hope this helps and hope I can help you. Just throw a tech-day at your house; we'll have a good afternoon. (don't forget the beers, guinness for me)
