DHL International Shipping Calculator

I need a link that can be posted in an eBay item description. This link should bring up a new window when clicked (not closing the ebay window or tab), the window containg a DHL International shipping quote generator. There would be one field, a place to specify your destination country from a drop down window, only countries that DHL ships to. The other field (originating country) would default to the United States, all shipments will be coming from the US. The box would then need to retrieve shipping information from DHL. Also if it could be a smart generator and be able to ‘know’ the price of the fixed price auction that it was linked from to add shipping insurance to the quote automatically that would be helpful. I would need any hosting for this set up as well. Also auto update to the latest DHL quotes will be needed to make this system maintenance free.
