Satin Black Paint

The 72 Duster is in for paint and the body guy is having difficulty getting a premixed paint or a formula for a VOC matte/satin paint. Any suggestions on a formula? No he has not done this before and yes he is a really good body/paint guy.Because we live in a rural community there is not a lot of choice and difficult to have paint shipped. Any help would be greatly appreciated. Thanks!!!!
