Share automatically RSS on Facebook Linkedin Pages e Groups

Automatically Share RSS in and Groups of Facebook and Linkedin Pages I need a script that can share RSS on Facebook pages and Facebook groups. Linkedin Pages and Linkedin Groups the script has to share the rss items in the pages and groups of facebook and linkedin The script should be able to configure the amount of rss items that will be shared and refresh interval for each rss. I need to choose the nescessario time to interval for each rss and a custom message that should be created when I put the rss. The script should analyze rss and always publish new items, if it does not have to wait for new items. If there are no new items in rss it should not share on social networks. I need in the RSS configuration that I can choose which page or group the item will be shared. The script should load all the pages and groups of the two social networks and list so you can link the rss with the pages or groups to me Example Rss1 will share page 1, page 2, group 1, group 2 rss 2 will share in Group 1 of facebook, group 2 Please send your proposal with the correct value of this project without increases afterwards. Correct time to deliver it, at least for testing.
