Such places do pop up from time to time, but they never seem to last long! A quick Yahoo search listed one in Aberdeen, but the link just gave a 404 error message.
I have a vague recollection that one of the big companies, Halfords or similar, was planning such a service, but I can't find any reference to it. I suspect that, by the time you've covered all the costs, the rate you'd have to charge the punters just doesn't make it wothwhile.
(Edit)While I was typing that, grandslammer posted his reply. Wonder how much they charge?
