If you look at the "find a surgeon" tab in the to right of this page, you can search Mexico and reach Dr's there. I was able to find several that do rny, as I had the same question as you. Dr Joya, as the nice lady said above, I have heard all good things about. He currently offering rny for $9000, without airfare, but that does include everything else, including a stay in a beautiful resort in Puerto Vallerta overlooking the ocean. But I see you live in CA, it would be much less expensive, for you to fund a qualified surgeon in Tijuana. Dr. Ramos Kelly is who I am looking at now
