Replacement Clutch For Gen 6 St202

[Applellial]

I've got a gen 6 UK spec st202. The original clutch started slipping at around 108k miles and i got it replaced by Mr Clutch who skimmed (or told me they did) the flywheel as well. It went back after around 12k miles as the clutch had started to judder under load. They said they replaced the clutch with another one (as it wasn't adjustable). Since then the car has done around another 9k miles (spent over a year mothballed in a garage whilst i was abroad so warranty is out of range now) and it's knackered again. Went to pull away quickly at a junction tonight and all i got was a bag full of revs and not much movement. Once the revs dropped it would drive ok and i got a good waft of burnt clutch. It's obviously knackered again. So obviously somewhat miffed that Mr Clutch put not one, but two lemon clutches in it. Not much i can do about that now but i need to get it fixed. I have had a search on here and a DIY job isn't really an option for me as don't have the kit to do it, let alone space to work on the car. Anyone recommend either buying a good clutch (and flywheel no doubt) and will garages fit it for me? I'm in watford area if anyone knows a garage they would recommend.

thanks
