Develop an auto&manual feed from Wordpress to Rightmove and Zoopla

Hi, I am looking for someone who can write a wordpress plugin that will allow an automatic or manual upload of of letting properties to Rightmove, Zoopla and Findaproperty (if possible). Only the Zoopla and rightmove are critical. If it's complex to do the auto upload a manual upload will suffice. The project is not confirmed yet, but we will most likely use wp-property plugin for Wordpress, plus perhaps wp-crm and wp-invoice. We can provide full admin access to the wordpress install and FTP access, once the project has been agreed. Thanks, Chris
