Custom web pages integrated with OsCommerce-based website and MySQL database

This project is to create custom web pages on an existing OsCommerce-based on-line retail website. 1. Create employee management page Employee info table ('employees') already exists in MySQL database. Need a page to create/update employee info by administrators(administrator users from OsCommerce/MySQL 'administrators' table). 2. Create check-out page. This is not the online customer add-to-cart checkout page. This is like store cashier checkout or library checkout interface (used by staff, not customer). But it does have add-to-cart feature. The checkout page should: - be accessed by (employees and admin) login credentials (i.e. checkout page can't be open if login is failed). Use 'administrators' table and 'employees' table in existing MySQL database. - have a search section containing searchable fields. - have a listing section to list the search results (if searching returns multiple items). Each search result should display brief info such as item name and have a 'add' button to add to cart (in case customer buys multiple items). - have a checkout operation section to perform the checkout of selected item(s). This section should list all items customer chooses and contain more detailed product info (name, stock number, price...), tax, coupon discount and total price. - after payment is set, new order should be added into MySQL database and should be viewable and editable in OsCommerce Order Management. - generate and print receipt after checkout Employee login page and checkout page don't have to be part of the OsCommerce. But both should be coded in PHP, HTML, Java/scription, SQL, etc. New order should be added to corresponding order tables in MySQL and viewable/editable in OsCommerce admin panel order management. Check-out page sample interface is attached. Bidder should be an expert in OsCommerce, PHP and MySQL. Documentation: should provide a list of new files created and modified files.
