Need a voucher code module for Gallery3

Please only apply for this project if you have proven experience programming a Gallery3 website. I need a voucher code module integrated in my Gallery3 website [login to view URL] Two of the seven voucher code characters will identify the value of the voucher. The other five characters will identify the referring client. The module will be able to: - store the referrer by name and post code (that's a zip code for those who come from the former colonies); - store the new client by name and post code; - store the product(s) purchased; - apply the discount in the shopping basket; - do the arithmetic; - make sure the client is charged the right net price; - send me a report of each transaction by email; - allow me to download a complete report of such transactions using start and end date as parameters using UK English. UK date format dd-mmm-yy is required. I will provide a database of existing customers as a csv or txt file - your choice. I will need to be able to upload additional customers as new people buy from me. As these customers may come from other sources (e.g. Amazon, EBay, I must be able to add individual customers manually either by a data entry screen, or by adding them to the csv database and re-uploading. I ignore bland "Let's do it" bids - please do not insult me. I ignore generic bids - please do not insult this website. Please state the URL of at least one, and not more than three Gallery3 websites on which you have previously worked. I can identify all Gallery3 websites by their logo on screen. Please do not give me more than three examples. If you cannot understand that simple instruction then you can't understand what I am asking for. I will need the work completed within 72 hours fo awarding the project. You must have Skype available and be able to discuss things with me on Skype during my daytime - GMT (London, UK). No bids from Islamic countries because of adult content. No bids from the USA or US dependent territories because of USC2257 and SOPA No bids from countries where the UK Government has imposed a trade embargo.
