We need a simple script developed for coupons. Script is very simple. Purpose of the script is to allow customers to put small piece of generated code on their websites and show coupon code.
Customers will have a list of coupon codes: basically one code per line, on a text document (that comes from Amazon). After a login to script interface, they will have ability to upload the list in a text file.
Script then generate a code like iframe or java or whatever that can be inserted on any web page which will display the coupon codes one at a time.
Each time a new visitor goes to that web page (wit built in script generated code), a different single use coupon will be displayed, sequentially. Once a coupon has been displayed once it is not displayed again, but the next in the list is displayed. Once the coupon codes are all used up, a message displays saying "Sorry, this offer has expired. All coupon codes have been taken."
Script should be easy to install on linux server as it will be installed on several servers. We don't want this to be any kind of WordPress plugin - script must be standalone and have some basic install interface. Basic admin and fronend interfaces also.
Customers must be logged in in order to access script. Customer registration must be automatic. Our payment system (probably Nanacast) can send notification to a specific URL in script which will allow customer registration.
We also need an admin area where we can manage customers (lock user access, create new users etc.).
This is just a brief description of what needs to be done. All details will be explained after you have been selected for this job.
