I'm a big fan of massage and massage parlors in general, so I say go for it.

 
As to nuru, here's the thing with that:

While nuru is very sensuous, it is water based, and therefore begins to evaporate quickly, which leads to the massagee being chilled and uncomfortable.    The only really good guru massage I have had was on a sweltering hot day when the chilling effect was welcome.  In fact, it was one of the greatest session in my life as I look back on it.

 
So, if you do offer nuru, have a sauna like room to offer it in.   That should allow for a mutually enjoyable experience.

 
By the way, nuru is a great lubricant for things like anal.  It's not greasy like KY, and doesn't stain, or adversely affect lates condoms like oil can.
