Website with integrated payment solution

We are looking to develop a website to sell digital product (non-tangible item) Website needs to have a very enticing and attractive landing page Website needs to be setup to work with our payment gateway, First Data Payeezy. This gateway supports a credit card feature called "soft descriptor". A soft descriptor allows us to pass through a name different than our merchant name to appear on the customer's credit card statement. Our merchant name is just our corporation name, but using the soft descriptor we can use the name of the digital product that we are selling to help the customer remember what they bought when they look at their credit card. The gateway includes APIs, etc to make this job possible. All credit card transactions must go through our website - WE DO NOT want to use the hosted payment page that the gateway provides. We want to keep the customer on our website at all times. On some of the digital products we want to allow installment billing. So for example, if the product is $100, we want to create installment/recurring billing to allow the customer to pay a certain amount over a period of time (for example: 4 easy payments of $25.00 each). Each product we sell must have it's own unique landing page. We can use same landing page for every product but we will just need to modify the content on the landing page to describe each item and the selling points of each digital product. Example; Our name will be something like [login to view URL] 1st Digital product will be [login to view URL] We will create a forwarding domain [login to view URL] and forward to [login to view URL] 2nd digital product will be [login to view URL] forwarding domain, [login to view URL] and forward to [login to view URL] etc.... If you have no github or portfolio, don't bid.
