Drop Down Selectable Search Engine

[Sribeiro]

Hello All, I'm absolutely stunned by my clients request and require the assistance of more savvy developers on this.

My client wants a Search box that contains to fields - [1] Business [2] City.
When you click on the "Business" field a drop down menu appears with all the options available, you then choose the businesses you are interested in. Then you move on to the cities you are looking these business/es for, when satisfied you hit enter a complete list matching your selections appears in a formatted page.

Would anyone know of anything similar out there that I can learn from, or can someone give me a list/map of how I should get started and what to do?

Here's a link of a moc-up I did to show what I'm talking about - http://www.marcusgroup.com/test/imag...hSelection.jpg

Thanks, so, so, so much in advance peeps.
