Build Hotel Web Booking module

We need to develop a front end in html / css that will target our BE through some simple API's (http calls) to make bookings for hotels. Basically it must have: 1.- Embedded HTML > this is the initial form that will be embedded in the hotel website where the user pics the dates, how many people and clicks book now. 2.- Availability view/page > Display the results of an availability search between certain dates. This is the page where you will see a list of rooms available, images, some descriptions and prices. 3.- Booking page > one a selection is made from the availability page you should be prompted to input the user information, address, credit card etc. 4.- Confirmation Page > displays the final booking number along with a recap of the reservation. Basically all the information that must be displayed will be fed by our BE, so you will do a request call with certain parameters (e.g. how many persons and dates) and the BE returns in JSON format a list of available rooms with all the necessary information along with links to images that must be displayed. We would like to develop 3 different looks with the same functionality. Thanks, Luis Villanueva
