Banners for an e-store of women clothes

We start a new online store of women clothes. That's why we need a graphic designer for ongoing project. Mainly we will need banners for our main page but also we may need to create a design for our Newsletters, brochures or even advice about site design. We want to find a designer who creates a unique style for our store in his banners. It has to be very feminine, fashion and stylish and to look very professional and modern. You may see our site here: http://dd-atelier.com. The site isn't completed yet but you can see our old banners there. We do not expect the designer to copy our current banners style (although we don't want to change it dramatically), but we want you to offer to us your point of view. We need mainly a graphic design but html or flash skills will be a plus. Sometimes we may need not only static banners but interactive (with buttons or interactive forms) as well. We will need a designer for a permanent work, we want to find it once for a long time. Usually we need up to 5 new banners a week (March-May and August-September). Other time there are less of them or even none. But we need a designer to do his job fast (within a day). We expect to see your portfolio if you bid. We are mainly interested in your experience in feminine sites design or banners for feminine sites. Or you may do your test banner for us to show your abilities.
