How do the costs and results of a floating abdominoplasty compare to a traditional TT?

I'm having difficulty finding information on FAB (floating abdominoplasty). How can I search for providers who perform this? I am curious how the cost and results compare to a traditional TT. I am in good shape, at ideal weight, just have stubborn belly fat. Prior c-section. Prefer St. Louis, MO but could travel. Also wondering why this procedure is not listed on Real Self. Thanks in advance.
