WordPress Adult Site Landing Page Optimization (Single Page)

I already hired a freelancer to redesign my WordPress landing page, but I'm not completely satisfied with the final result. This landing page is a very important part of my business, so I'm looking for an experienced developer/designer who can refine and perfect it...
