Cam Belt - Garage Required

Hi All

The time has come to have the cam belt done on the Track Toy 197. As I am new to the area Northampton/Oxford (NN11 Postcode) who do I use to do this work? As close as possible as it is not road legal as yet (pending) so am looking for somewhere I could drive it to when it's MOT has been done.

Any ideas who I can trust it with to do a good job?
