There was a attempt a few years ago to set up a regional service under the Regional Medical Physics banner. They tried to recruit engineers from the X-Ray companies - but everything suddenly went very quiet and we never did get a regional service !
I don't believe you can give a full service on all the equipment in just a hospital, you would have to throw the net wider. I doubt if it could be just one or two people either, because there is such a wide range of stuff by different manufacturers. You would also have to offer a 52 week / year cover.
