yet another question about classifieds....

[demdev]

I've trolled through a LOT of resources, both on here and elsewhere and haven't found a definitive answer to my questions. I want to implement a Classified section similar to the one here:

http://www.theoutdoorstrader.com/classifieds.php

I assume the majority of it to be simple enough, with standard markup and CSS, however, the actual form triggered when you post a new ad has functionality that I haven't seen in any of the available mods out there. One being the integration of a Google map based on the zip code, and the drop menu to choose the category in the forum threads to place the actual post.

My questions would be, is there a mod, hack or paid product anyone knows of that would make this form easier for me to implement, and is the actual Classified section, as it appears to me, just html/css inserted with links to the threads for each category? I have the ability to work with most of the code, but no background in vBulletin, and was hoping to get some useful feedback from the group here. Ultimately, I believe I can create the necessary PHP template page for the Classifieds, and build it out in HTML, with the category listings, but the form has me stymied. I need that function, and am uncomfortable with trying to integrate anything into a new environment.

Any thoughts are and will be greatly appreciated.
