before someone bites your head off, Ill say it! if you have a look at the top of the 'wannabe's' forum there is a STICKY thread, it will have lots of the info you want, take it all with a pinch of salt though its only what other people think.
I used to instruct at ravenair, and still now a couple of the guys, all top blokes. pop in on a rainy day and they will sit for hours with you, but if you go in on a nice sunny day, dont expect much attention (theyll all be flying!!)
have you considered barton, probably closer to you if your from bolton. ravenair also have a base there.
if you have any spefic questions after reading that sticky feel free to pm me
