48 hour countdown code

I need a code writtenand uploaded to my web site as follows: I will be running a sale and I want every visitor to my site to have 48 hours after they first visit the site to get the discount - so I assume the code will need to place a cookie on the visitors computer which counts down 48 hours - during the first 48 hours - when they return to the site they should go to the site displaying the discounted price... ...but after their 48 hours have passed, when they go to the site, they should be automatically redirected to the site which displays the normal, non-discounted price. If you know of an easier way to do this - please let me know. The final product needs to be loaded to my site - so the job is to create the code and make it work with the site. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows: a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
