PHP Coupon Script with Automatic Installer System

I am looking for a coder to build me a coupon script site (using preferrably PHP, CSS, and AJAX). Here are some of the mandatory features I am requesting in this script: 1. Ability to organize Deals/Coupons by Stores, Categories, and tags. 2. Search Feature: Allow visitors to search the website for specific stores/coupons/deals 3. RSS feed for the site 4. Admin panel. Manage all of your deals and coupons on the site site through the admin panel 5. Delete expired coupons, or deals with any other criteria you select via the admin panel Essentially, I would like the structure of the coupon script site to have a 3-column layout that looks similar to: http://www.BensBargains.net. Design needs to be crisp, simple yet elegant and user friendly with a business color scheme. Complete Feature List can be found here: [login to view URL] --------------------------------------------------------- Please provide a realistic bid for the price and a serious estimate about time needed, please note unless you can do it in the time you estimate, DO NOT promise what you cannot deliver or I will definitely cancel the project even if you worked hard but bid unrealistically on time, no false promises please. 50% will be escrowed on project begin and remaining 50% when its completed. Deliverables: >Fully working script with all functions described above. >Script should include an installer system for easy installation on more servers, an installer like wordpress blog installer or similar installers used by other scripts >Testing should be performed by programmer before submitting the script, testing should be clean with utilizing all features of the proposed application. Members ids should be signed up, coupons should be posted and viewable so I can easily check if all functions are working. > Constant feedback needed about progress of the project. ------------------------------------------------------ Please begin you bid or message with word 'COUPON' so I know you read this. Only realistic and competitive bids please and no false promises please, as they will waste both our time. Thanks!
