Virtual tour script (frontend/backend)

I need a simple listing administration with property web pages. It has to be very simple so the page is generated easy and fast. A new page is generated when listing is saved. There are only few data for each listing, all listing/pages will use same template. Please try to avoid wordpress with tons of slider plugins, I already run this project for third time and the one delivered in Wordpress was not really usable. I am able to do the final design myself, but I really need a good and simple backend + basic frontend. 1) add agent a) fill Name, Telephone, Email, Company, Website, Address b) Upload photo 2) Add new listing a) fill address, price, nr of bedrooms, nr of bathrooms, square feet, open house info, description text b) upload photos c) assign existing agent 3) After saving listing a) a new url is generated automatically: [login to view URL] (each listing will have different url) b) all the data from backend are projected to the page, using the same template c) if open house info is missing, do not show the whole segment 4) page template looks similar to this: [login to view URL] a) all house info and agent info are in one block, which can be minimized b) slider has to be responsive, must use panning c) under slider, slideshow thumbnails are shown d) slideshow plays automatically e) in upper right corner, there is Mute icon to mute the music f) map will use specific javascript design overide - will be provided g) slider and thumbnails will always be on full screen - 100vh h) all thumbnails are clickable and the picture will apear in slider when clicked If you know how the virtual tour pages look and work, it should be an easy project for you. I am not transferring more than 10% milestone in advance. I did this project before 3 times already, and got burned twice (project not finished and money not sent back.. ). Thanks for understanding
