DHL Intraship label add-on for cs-cart

We're running a cs-cart shop in Germany and would like to have an add-on that allows us to connect to DHL and print shipping labels straight from our shop. It exists (even for free) for Magento and Oxid so maybe you can take those modules and use them as an example. Here's a link to the one for Magento: [login to view URL] I already have an add-on for UPS - maybe this can be taken as an example for the cs-cart integration. I have access to DHL developers corner - some stuff is in German though, but the API's should be in English. Best would be to get someone with both cs-cart and dhl intraship experience, cause both are apparently quite peculiar programs. If you speak / read German that would be a big advantage, because support from DHL will be mostly in German.
