I need someone to add discount coupon capability to my oscommerce site.
It is heavily customised, so I need someone who knows their way around oscommerce, and has integrated addons onto existing sites before.
No pages (php or otherwise) can be replaced, but you can modify/add new pages. All existing functionality must continue to work.
The coupon code needs to be entered somewhere where the price is visible, and after entering the code, the price will be corrected showing the new value that will be paid.
On the admin side, I need to be able to enter a start/finish date and the code itself.
Note that, as the cost calculations are non-standard, it may require some tweaking to get this to work properly.
Full access to catalog/admin/mysql in a staging environment will be given to the chosen bidder to make the required changes.
Please submit estimations on time required.
