76235 Reciprocal links adder

I would like to set up a script on a main site of [login to view URL] where people can come and select from a number of sites whether they want a reciprocal link to theirs. eg: Choose which sites you would like a reciprocal link with: [login to view URL] Tick checkbox here: [login to view URL] Tick checkbox here: [login to view URL] Tick checkbox here: etc. Then, when they have selected their choices and entered their email address, their own website URL and where on their URL our link will be located, I'd like the script to add them automatically to the links pages on the sites by ftp. Next, I'd like the script to check against the latest additions to the list at intervals of 48 hours and 96 hours to check if the reciprocal link has been made and to send a reminder then to remove the link automatically after the 96 hours if the reciprocal link has not been made. For a similar example of the form - [login to view URL]
