Where best to get a seat cut down? (East Mids)

[Digdug]

I need to get my Fazer thou's seat cut down a bit (actually mainly cutting out width at the front, as well as a bit of height) to accomodate my short girlie legs. I am too scared of wrecking the seat to do it myself with the electric meat carver 

Can anyone suggest anywhere in the East Midlands that would do a good job and also not too expensive? I am near Loughborough, so somewhere in Leics/Notts/Derbys would be best. Cheers
