URGENT Open Realty Modifications

I need a quote and a timeframe of the follow: What I need done is a dynamic menu system addon. The menu system will be 2 tiered. Once the top level menu is clicked, a submenu will open up underneath (it's horizontal). The submenu will also stay open when you change pages and open to the correct property class on the menu. So if you click on Top menu 1, it will open and you will see prop class 1, prop class 1 will remain open on the next page. I need the menu to open up to the correct property class when a property is selected. ![][1] I was thinking it could be a sql call based on property class, but I am unsure on how to implement. This is very time sensitive and extremely urgent.? ? Please show examples of Open Realty work.? Price is not the determining factor, but quality of work.
