Customisation of JXtended Catalog component, RSS feed

I currently have a client site([login to view URL]) running Joomla 1.5.25 ... the site listings are based on JXtended Catalog component (no longer developing / contactable). I require a developer to: a) Fix the Catalog page navigation (doesnt update to next page properly) b) Create an RSS feed based on Catalog category, which will also feed through thumbnail c) Allow PDF to be created based on pre-defined filter, so user can generate and download an up-to-date listing of items in the catalogue at any given time - format of PDF to be similar to on-screen catalog listing (i.e. thumbnail, then item description) Work needs to be done urgently, so need developer ready to start work straight away .. must be a good communicator.
