Minolta XD-11 CLA / Repair Resource

I have a Minolta XD-11 that I've had since I bought it new in the late 70's. Of late, it is cycling slowly although the shutter speed appears to be OK. Can anyone recommend someone really good to evaluate, CLA or repair this camera? It has a lot of sentimental value and I would really prefer to repair it rather than find a replacement. Beside, I could find myself in the same or worse position with a replacement.

Thanks in advance.
