discount sites that pull savings from central database

Coupon website development *Website design with the normal required info similar to [login to view URL]******** .com accepts with our name and maybe a little nicer design. *Customer needs access code to be permitted to the backend to view and utilize different coupons that are available with his offer. *Customer will then register with his contact info and can then begin to browse for savings. Admin *Will set up codes to be given out to customers either manually inputted, randomly generated, or consecutive numbering, and this list of access codes can be exported to be used to distribute to customers. *Admin will be able to set up for sets of codes an activation fee, in other words while registering before they gain access to discounts they might be required to pay a processing fee or activation fee. *Codes will be given a valid time until expiration. And/or a value amount. Value will be based on coupon amount that is entered or if it requires some money that must be paid by the customer, than the discount that is given from regular retail price to what they will pay is deducted from their amount. *Will be able to put in coupons into a shopping cart for customers to select, you can see an example of this by g*******.com , browsing discounts and picking a coupon product you want delivered. *Will be able to set up other coupon links that will go to other third party sites or databases that the customer will be able to use with no limit until expiration of their access: *Will be able to list coupon deals in the appropriate categories an example of this if you go to n***********.com *In addition where available we would like to put the third party site in like a frame within our site. (where available) I can get you access to n******.com to see how they do it. Coupon Database. *We would like that whatever coupons we load up we can use for a number of different sites that we will later build, for example g*****.com, gro*****.com, c******.com, and on********.com are all one company but their grocery coupons on g*******.com is really the same coupons they just market a different way with the same coupons some get a certificate and is free , some require when you order coupons you have to pay processing fees, shipping and handling, some they can purchase a membership. I want it to be set up that I can add different marketing strategies as well as have the ability to allow certain offers accessible to one group but not the [login to view URL] example if they get a grocery card so we may allow them to get access to grocery coupons and also restaurant coupons but not travel discounts. Etc…. Customer Database Be able to search for customer in database by the normal methods within a certain period of time etc.. See customers account info etc… Be able to send emails to all or select customers. Be able to search access codes and get reports how many new people came gained access and to export access codes or what we can do for each series of codes we can attach letters to the beginning of each code and we can get a number for how many of each set have been redeemed let’s say each month. Payment method I will use pay pal and credit card through pay pal I am looking for someone who has experience and for the right person this should not be too difficult, you may modify a shopping cart or other CMS to accomplish the objectives. Please tell me how you will do the required objectives and how long it will take. *****these are website examples of what I am talking about they are blotted out but will give the web address in pm as well as further documentation.
