Build an 1 page Online Store.

I already have one landing page that I want to convert into a selling Landing page, meaning I want my landing page to sell files for download. The current existing landing page is [login to view URL] I want the above landing page to be redesigned for a more appealing sales pitch and also able to receive credit card payments and then let the customer download our software and also send him to our portal that is already configured on the current existing landing page. Example to be benchmarked: [login to view URL] This job will consist of 3 etapes: Etape 1: Make the landing page with sales pitch and operational and able to get paid with credit card and other main payment methods. Etape 2: Create google adwords campaign with payments PER ACTION, where the ACTION is triggered only WHEN the user PAYS to get our product. Etape 3: Operate the campaign until it gets at least 30 legit payments from customers. Our product consists of 1 excel file and 1 PDF Manual on how to use the Excel File. Included in the purchase price is a 1 year subscription to our portal, where the landing page doesn't need to manage this subscription, this will be managed manually. The price for this amazing package will be the double of what we will be paying google adwords on the CPA campaign. Our Warranty on our product is a 15 days money back warranty, no questions asked. So you have read until the end of this post, please make your bid saying "I am ready to create a 1 page Online Store" When you type your bid, please suggest how much $ you belive we will have to pay adwords to sell this product for us. Send us links of similar projects you have already done, PLEASE, ONLY 3 Links that MATCHES what we are talking about here, DO NOT SEND 100 links about OTHER things that has nothing to do with this job !
