Floor tile job

I have a floor tile job that needs to be done fairly soon. It's about 800 sf of 18x 18 travertine tiles. I'm wanting someone that is a professional and can do this right. It's new construction and floors are flat OSB . I will buy all materials. Looking for a labor price. Send your credentials and an approximate labor price per square foot. I also have shower surrounds that we can talk about. Thanks!
