I'm looking for someone to design a clean, sleek mockup for improving the interface of an already well-built, popular AJAX web portal package. A web portal is like iGoogle and Netvibes. I only need a mockup as PSD, so no development is needed. How much should I expect to pay for just a mockup? Web portals typically don't involve many distinct pages because each tab usually looks the same. Would any firm out there do small jobs like just mockups? I've run into a few, like Blue Flavour, but their minimum budget is around $10,000+. Thanks
