CURL/PHP Project - Autoform Fill + Sumbit, & Page Navigate

Hi The target site is [login to view URL] You will notice the barcode and pin fields. We will supply these to those that PM us. We need a script that can run by cron jobs, that will login to the site and carry out one function (navigate and press 1 link). This is to renew the books. Image 1 shows the login page. Image 2 shows the page straight after login, the red circle link needs to be followed by script. Image 3 shows the page from the link in Image 2. The "Renew All" link needs to be clicked. Thats all. Low budget simple project, Please post bids and comments. Should be single file script that can run on cron jobs.
