Build Me a Web-Based Software Tool for Amazon Products

Looking to create a software that automatically populates pre-made landing pages with information that is entered into the software tool. Landing pages will be pre-made (landing page w/ coupon, pop-up for email opt-in, thank you page, expiration page, etc.) In the software, a user will put in information about their product: product name, they will choose a landing page style, normal full price of the product, start and end dates of the campaign, email software information, and other information. The software will then populate the landing page (based on which landing page style was chosen) with all the provided information. Additionally, users will upload one-time-use/unique coupon codes into the software. The software must ensure that a different unique coupon code is displayed to each unique customer (based on IP address or some other unique identifier). Software should also be able to provide multiple price points and sets of coupon codes within one campaign, so that one customer may see 44% off price when he lands on landing page, and another customer may see 50% off, for example. When you bid on this project, please reply with the words "Amazon Gains" so that I know you've read the entire description. Please give an ACCURATE timeline for how long this will take to complete. Be aware that NO payments will be released if timeline is not met, so it's better for you to be honest about time it will take to create this software and everything that goes with it.
