Don,t you think you can do it yourself with the help & advise from the fellow stovebolters. These brakes are pretty basic.
When I started this reply I didn,t realize you were a woman. Then I thought if I changed it I would be a sexest. So the advice stands if your husband can/will help with the heavy part. If you don,t do it yourself I believe I would find a private shop. There are probably some bolters in that area that would know of some. The big chains/franshises have only your money in mind. These older trucks take a little more time then regular production jobs.
