The professional mature model group, the GMS (Great Model Showcase) is seeking one photographer to fill out the company of four accomplished photographers for a two day group photo shoot, "Viva Las Vegas", the 2021 GMS Group Photo Shoot, May 21-23 in Las Vegas featuring eight mature models of the GMS. We will announce a major sponsor for the shoot on March 24. 
This is NOT a "shooting gallery", or "shoot around". The four photographers will shoot one-on-one sessions with each of the eight models over two days. The first will be at the Sinatra House off the Strip, a mid-century 1800 square foot home decorated as an homage to Frank Sinatra and the "Rat pack". Sunday, the photographers will set out to shoot in the wild, in and around Las Vegas. 
A group get acquainted dinner at a fine restaurant, and accommodations at the host hotel are also provided. A video documenting the shoot, with opportunities to be interviewd, will be shot throughout the weekend.

sound great, but what is the cost?

Found the cost at the photograpers page, $375.00 is not a bad deal, for that shoot.
