Entertainment portal launching

We're working on a new entertainment portal which is scheduled to launch in late-April/early-May, and need to find a suitable London-based partner agency, who will be required to build it. We have a usability/HCI consultancy designing the interface/functionality/architecture. The selected partner will be expected to build the site to an agreed deadline based on the provided design document. The site is being designed to be accessed via PCs and mobile handsets, so experience of developing WAP portals would be a bonus. The site needs community features such as messages boards etc and will link to other white-label areas such as betting and wireless games/services. We need to be able to publish articles on a daily basis, so a good, easy-to-use publishing interface is a must. Please direct initial expressions of interest to elementsofdrag@hotmail.com. We are about to begin our first funding round but this will not impact on our launch plans. Agencies prepared to exchange equity for fees for the launch phase will be particularly welcomed as we want to channel our resources into a launch marketing campaign. Please forward relevant URLs and a ballpark quote and timeframe for this kind of project. London-based agencies only please as the project is time critical and this is where we are based. Also, particularly in the case of equity partnerships, we want the affiliation to be long-term so that you have an interest in producing a showcase site and can benefit from our growth. The venture is global in scope and has a revolutionary concept that drives its core revenue streams. We will respond to shortlisted applicants within two weeks. Many thanks.
