As a recent reconversion to the joys of flexwing flying, I'm sure you'll have a whole lot of fun.
I don't know any of the schools in that neck of the woods, but the BMAA website has a directory and in my experience whilst some can be a bit laid back in the housekeeping pilot, I've never yet seen a microlight school less than completely enthusiastic and competent where the flying training was concerned. So, picking whichever is nearest is probably a good bet.
