If you're after a great job the give Simon'n'Stu at Crash Corrections a bell on 01795-580937. They're based on the Isle of Sheppey which is where i'm from (handy having a great outfit like this on the doorstep!!!) and did a brilliant job on my S1 that's still as good to this day and my 3 door Cosworth is going down there next week for it's re-incarnation. Both jobs are sensible money for the amount of work that's being carried out and as they're entusiasts rather than bodgit and scarper mungers this is reflected in their work.
The only downside is the amount of time it sometimes takes to get the job done (they can be really busy at times) but at the end of the day i think the finished job is worth waiting for.

Hope this is of some help to you !!!
