I'm in a somewhat similar situation, except that I hope to be getting my ME commercial and single soon. There are several schools that do it, and I've heard good things about them on this forum and not only. In CA you have Grey Eagle, FlyCorona, (though other schools would gladly do it in an accelerated manner), in AZ you have Sheble, there is White Air (don't know the location), in KA? you have Prairie Air Service and the one I've decided to go with is OS Aviaton in NC.
Most of them offer a program of 8-15h of flying which takes anywhere from 2 to 10 days. Again, I've not tried any of them, but these are the ones I researched and have decent prices. I'm sure there are many others, probably most of the schools with a twin would be willing to do an accelerated program if that's what you want.
