Automatically Post To Elgg Sites

Hi, I'm looking to hire someone for a job if possible. Basically, we have a network of Wordpress blogs, Drupal sites and Forums. We also have 200 Elgg sites that we would like to update automatically and link back to posts made on all of the other sites in the network twice an hour. Each Elgg site will have 55 specific websites it needs to link back to. It can either generate a snippet of the content and link back to it or just post a link directly back to it in the form of a blog post on the Elgg site. It can't, however, do so via a Wordpress plugin or via a cron job. Perhaps XML-RPC is possible? I'm not a coder so I don't really have any idea of the best way to approach it. If you do have any ideas on how to do this and would like to do this job let me know. Additionally, if you think this would work better with a different CMS other than Elgg we are open to ideas.. P.S. The job will need to be complete within 10 days. If you are able to complete the project sufficiently we will also use you for another project that we are looking to complete. [login to view URL]
