Automatic Ticket Grabber (no credit Card)

We are looking for a programmer to develop a system/robot for us to make reservations. The target site is [login to view URL] and you need to make a reservation for a specific museum (list of 4 items) and for a specific date Therefore, through a BackEnd, the system must allow the admin to schedule a purchase (via cron) considering this information that the site gives: - museum type - date hour - number of participants When that date and time arrives, the system will make the reservation The reservation is not done with credit card but it's taken from a pre-paid plafond.
