I know its not Surrey or Hampshire but one visits regularly at Ian Macqueens, Devizes and I nicer vet would be hard to find (orthopaedic) also I believe there is one (permanent or visiting) in the Guildford area, again I think it's an orthopaedic specialist. Good luck.
I have details of a woman who scans in the Hants area, not sure how far out you are to where she normally operates. Shes based in Liss. Im about 18 miles from her and she charges me £40.
If your interested PM me and I'll pass on her number.
