Two landing page designs

Kind of design: Landing page
Num. of web pages: 2
Ideas for the visual style: Style based on existing page
Extra notes: I have two wireframe mockups that need turning into designs for a landing page.

I have had a conversion specialist produce two new variations of an existing pay per click landing page, however I am not a designer so I need someone to create PSD mockups that I can send to the developer to be coded into a new page.

Preference will go to those who can point to previous landing pages they have designed, and who have an understanding of conversion rate optimisation.

There will likely be ongoing design work for the right person.

The budget is indicative only.

Thanks
