Are they charging you for requests (over the initial allotment of 5,000 requests per month), if this is done via Bing Web Search API in the Azure Marketplace?
iI felt the sameway . I just used various apis for unscatter.com you may want to see about getting access to the blekko api if you keep playing with it. iI use some of the slash tags they offer for some search views, it's real easy to work with.
