I have organized hosting and domain name. I want the latest stable release of OsDate installed and configured to work with paypal.

Also want to add customization so I can have Discount coupons accepted by system - The user who has a discount coupon can enter that when signing up or when upgrading their account and the system automatically gives them the correct amount to pay after deducting the coupon value.

Reasonable bids only pleaseI just wanted to clarify 2 things:

1) Osdate is already installed in Vanilla configuration on my server, so all I need is to customize it with the discount coupon script.

2)I don't have any script for the discount coupon - so winning bidder will have to either find one(if there is one floating around on web) or write one from scratch...

The coupons I plan to use for marketing. Basically they will be tool to give users special discounts. I want the ability to create multiple coupons with different dollar values attached to them so they can be given to affiliates as incentives to bring more users and some coupons to be used in marketing ads to bring in more paying users.

The coupons will not be given by registered members to others. They will only be given out by admin(me) to selected affiliates and advertised for marketing.

How I want it to work is like this:

Example coupon: AACCBB worth $5

The user when they join the site should be asked at the time of creating account if they have a discount coupon. If they enter the coupon code (AACCBB) and select silver membership which is normally $20 the the site should deduct the coupon value and give then $15 as the amount to pay.

Similarly if a registered user wants to upgrade from free account to paid account they get asked the same question and if they have a coupon then can use it to get the discount.
