Simple site with 3D models

I'm looking for someone for prepare simple page in HTML5 displaying 3D using Cesium engine and ION data. How should it work?: Site consists of two section: main (on the left side) and menu (on the right side). The main section displays model, menu section consists of many tiles (say up to 10) which allow to change models displaying on main section. The menu have to have slider if number of tiles is more than 4-5. If you pick one of them the model should appear in the main panel (left big picture) . Picked model should (be merked on the menu - the way of marking is up to you). The menu should have ability to hide and show again. What do I have?: I have already java script(s) to generate main window with 3D content. Now I put the script to plain html to display in web browser. I can supply few html's with different scripts to put them in the new page. Probably is the way to modify the script to display different models in main window. If you are interested in I'll sent html or script.
