Script customization.

Hello I have a Geodesic script. Was bought from: [login to view URL] I need to finish some parts: 1. Add ability of 3 level filtering/selecting. Meaning when adding an add or watching an ad the user will be able to select/filter up to 3 comboboxes. The first combobox will affect the values of the second and the second will affects the values of the third. For example: When adding an ad the user can choose from the first combobox "Electricity" The second combo will show all electricity (TV,DVD,Computers,...) when selecting from the second combo for example "DVD" the last combo will show "Sony,Toshiba,... As i said there can be up to 3 levels. Today i can configure only 1 level (in admin + site). Work on it already was done (maybe you can finish it instead of new one). 2. I have a "area" filter need to customize the search for ads. 3. Small changes (fonts,RTL,...). 4. Fixes or small changes for the work that the previous worker did. 5. Copy the site to a test site + move the test site + the current site to other Host. Thanks
