Create Website Mockups, PSD format design

I am looking for a talented web designer to collaborate for multiple projects. The designer has to deliver the mock-ups in PSD format that can be sliced and than coded. We are going to provide all the specifications and the elements the mock-up needs to contain. The first project is a design for a Travel website. Homepage will contain a header, a search engine for flights and hotels and more categories of travel offers (each category will have multiple listing). We will also need to design the category page, product page and static page. Please post your portfolio only if you are interested to work for multiple projects and establish a long-term collaboration. We have more projects we have to start right after finishing this first design. Our preference is to work with Romanian designers, but nobody is excluded.
