Local place/person for fork seal replacment 1150GSA

As it says really, looking for a place or someone local who can change the top fork seal on my 03' GSA. Phoned the local bike shop & they wouldnt to do it because it was a BMW!
I need it done so I can MOT the bike. People have said its an easy enough job but I've never done one before on any bike so need to see how it's done.
So any local bike places or anyone on here thats local that can do this job?

I'm in Coven, just off the A449 about a mile from jcn 2 of the M54.

I just found Steptoe's excellent guide to fork seal fitting, wasnt expecting it to be that simple. So I will now give it a go.

BTW I phoned my local BMW dealer & they quoted 2 1/2 hrs labour & £50 parts?!?

Seems like a lot of labour if it really is as simple as Steptoe's guide, I take it that includes risk assesment brief, Tool certificate check, hazadous work site brief & coffee breaks with work completion estimate meeting.
