Binocular collimation advice needed

[MK20]

I have a quite nice pair of Optolyth binoculars but the eyepiece focus is very off and I think they have a slight collimation error. Does anyone know a good repair shop in the US? These binoculars are about 1600 to buy new and rather hard to get serviced by the factory, so I would really like to find someone who knows what they are doing with the repair.

Thanks.
