Project Description:
I need a skilled PHP developer to make some modifications on PrestaShop (1.5.2) Order object:

2. display the "valid_until" property on the order's Products panel.

and to create a WebService (or extend the existent ones) to do the following:

3. get an "email address" and a "product_id" as parameters when called, then check on the ps_order_details table if a valid product is present and return a true/false result (a valid product in ps_order_details is a product whose "valid_until" date <= today())
