Daily Deal - Groupon module for opencart

We are looking to develop a module that integrates with open cart to be able to do daily deals and selling services generating coupons/vouchers. The coupons have unique ID which will be input by the merchants and therefore do the redemption Main specs: VENDOR -backend (login) -track coupons (see what they sold, and when) and redemptions -track status of deals (expired, ongoing....) -The vendor can have a simple app which reads QR codes and that links directly to the backend of the opencart marking that coupon as Redemeed/valid/invalid. VOUCHER - once the selling happen we send email a voucher with unique code to customer --> Action= generate the voucher + mail The code should have a QR code too. - Creates a coupon list in the customer account so they can see and download if needed or access from their mobile PUBLISHING OF DAILY DEALS: - Current opencart CMS --> differentiate by DEALS or products - Property : expiring date ADMIN - be able to store in the database redemeed coupons per merchant and per deal --> it generates a report which can be export or stored in the database (this is useful to know the payables to the merchant) - Report of status of the deals running / expired / finished and sales status We look for someone which had similar experience developing a module like that.
