Home Try on - Warby Parker Try on

We are looking to create a Home Try-On like the one shown on the [login to view URL] website. I need the ability to have a separate product page on my website where people can choose up to 5 Frames and not be charge anything. We need to be able to collect information in a safe manner so if in the event the customer does not return our products we can then charge them. The programming needs to recognize that 5 frames need to be chosen before anything can proceed. After the 5 frames are chosen it should take you a separate shopping cart" where they can enter their information and credit card info and the authorization is taken. We need to be able to hold on to that authorization or information until the items are returned back to us after their free trial. Also, we need a little front end help with arranging the site and making it simple but engaging. I am currently using a theme I purchased from Shopify which I like but I need some changing. I need the ability to make changes as need be (photos, artwork placement, footer redesign). I am open to used other mediums such as word press, etc. The Home try on and Product pages are the most important and need to work as it does on the warby site.
