476118 Voucher and Reward system for OsCommerce

for my existint oscommerce site I need: 1) Voucher system 2 types of vouchers: % discount and free product offer. when a customer enters a voucher code the name of the voucher will be included in the order if it is a product offer voucher or a % will be deducted if it is a % discount. ie FreeGRL1 will show a "Free Garlic Bread". 5%off will deduct 5 % from the total. Each customer can use one particular voucher only once. Admin: - be able to define several vouchers 1. define voucher Voucher Code Voucher Name Active/Inactive Dollar Discount FreeGRL1 Free Garlic Bread YES (no) NO 5%off 5 % Discount YES YES When a voucher is redeemed (at the checkout page) display the Voucher Name in the cart and add it to the orde! If a customer enters a non-existent voucher display his entry in the order as well. 2) Loyalty System for every Nth order add a reward name in the cart and add it in the order admin [login to view URL] rewards Rewards name number of orders Active/Inactive Free Coke 1.25L 3 yes Free Pizza 10 no front end when a customer logs in or when he returns back (auto login feature installed) display a pop up window/ 'Welcome back Roger. This is your 2nd order with us. Don't forget to redeem your loyatly rewards at the checkout page". at the checkout page show how many the customer has made order plus add a button "Reward Me". This displays a window (ajax) for customer to choose his reward. (ie when 10 order has been made offer him 'Free Coke' as well as 'Free Pizza' choices). Display the claimed reward(s) in the cart as well as in the order. 3) add pop up window when a customer requires minimum is not reached ([login to view URL] file) 4) add a map to the order (next to product and address) using google maps api according to a customer's address Looking for an experienced coder with fast turnarount and low price.
