I cost's about &163;100ish each to have them done. Maybe you could get in touch with one of the suppliers comming to stafford and arrange to
exchange your bumbers there?
I went to the Yellow Pages and found two companies. I live in Oxford and found one in High Wycombe who did a good job, but a bit far for you perhaps.
Have you tried Yellow Pages?
Otherwise, as yer man says, if you're going to Stafford you would probably find something / somebody there (tip - bring lots of cash with you! - raid
that piggy bank!).
