Compressor repairs

[JBUK]

I have a Sanden SD709 compressor off a BX that has leaking shaft seals.

About 8 years ago I had this job done on another compressor by a reconditioning firm in Feltham. They are no longer there. Anyone know of a company that might be able to do a recon job on this compressor for me.
I am sure that there are many companies that would be able to 'help' me by selling me a new compressor. The service manual shows the procedures and tools required to do this job. There must be some firms that still do this sort of work.
