Art Set Up Fee + error in checkout

We need an Art Set Up fee of $15 to be added to all orders that are shipped and displayed in checkout. This way we can take away the set up fee for gift card orders. Also, we are getting this error sometimes...when you try to buy someting 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '{1}19' at line 1 select products_files_req from products where products_id = 31{1}19 [TEP STOP] We will pay $120 for both tasks and instructions on how to install the set up fee.
