Advice wanted

Hi. My wife has been a hard, hard no for years, but this past weekend she's opened up to the idea of a non-sensual "4-handed" massage with a masseuse/masseur (hopefully) and me. She seemed interested and asked a lot of questions - what would you be doing? Would I be naked? What would you want me to do? etc. Small progress for some, huge for her.
I'm trying to determine how to set up something like this. We would want someone who would be okay with me doing some of the massage without expecting anything sexual AND not being weirded out about it. Any recommendations for sites I can go for this type of service?
