Designed theme for wordpress website required + included page structures and layouts

Right I already have a wordpress site hosted and almost up an running. Im actually spoilt for choices on Themes and design but i what i really need is a design which looks right for the type of site i want. The site in question is oldmastersgallery.co.uk. As you can see its pretty much a blank canvas

Its an art dealing site which focuses on buying/selling/ offering consultancy service to new and existing clients. The artists i deal in are the likes of Picasso, Monet, Goya, Dali, Rembrandt. to name but a few.

Some of the pages i require are Home Page, About Us, Artists list page, a good contact form page, maybe a page which has artworks for sale by which artists, im not sure but i have a few ideas. I also have some ideas of sites i would like it too look like but dont want to complicate it. Site should be user friendly i cant see why it should be complicated.

Also i think a fair price would be between £40-£70 for the design job though if impressed £80 and hopefully more work with other sites i have. good luck!!
