4297 server side rss submission

I am looking for a server side PHP script that will submit rss feed url's to rss feed services. The script will need perform the following actions. 1. submit 1 rss feed url taken from a text file and submit to relevant rss submission sites listed on another text file. When first feed has been submitted to all submission services, input a time delay and move to next rss feed on list. 2. Script can be run via CRON 3. Proxy support - proxies taken from text list of IP's/Ports 4. Seperate simple CMS for updating text files with new rss feeds to be added and new submission sites to be added. Ability to scrape known proxy sites and write IP's/Ports to text file for easy updating. Delete all contents from proxy text first so that ineffective proxies are removed. Ability to start script run from CMS and show progress. I can supply details of one multiple rss feed submission services. It would be helpful for programmer to suggest other feed services where only the submission of an RSS url is required.
