Develop device responsive landing page to complement an existing Instagram business

Require a creative front-end developer to build a responsive and interactive landing page to compliment an existing Instagram page/business. The business makes and distributes premium quality eye lashes, see [login to view URL] for inspiration. The landing page should be device responsive, single page app in style, preferably in the form of an AJAX app, using Boostrap4 and JQuery combination for interactivity. (open to suggestions in terms of plugins, but they should be licensed for unlimited use and at no cost) The landing page should allow visitors to register their name and email address, I will provide a JSON API that will receive a first name and email address, and respond with success/failure whereby the result message is presented to the user. The landing page should also display products (12 at this stage), in sequential order by id, each with an image, description, and cost, I will provide a JSON API that will return the product id, name, description, image url, cost etc. The primary channels for driving sales will be via social media i.e. instragram, facebook. Obvious links / hand offs to those sites are a must. Work can be completed in two components: 1) Design/Prototype. 2) Completed and functional landing page ready for hosting (folders,html, css, js).
