Add online gift card ordering to website in time for holidays

I'd like to add a page or pages to [login to view URL] that would allow people to order gift cards online. It is hosted by bluehost. I'd probably like to use Stripe as a processor and keep it simple. I'd love to get this done very quickly in order to sell gift cards for the holidays. We should also add a link to the existing website's header so people can find the page. If practical, allow people to buy multiple cards of differing amounts. I'd like the page to be mobile friendly. I will provide an image of the gift cards to use.
