I need a website directory fixed.

General information for the website: Online directory of treesurgeons
Description of requirements/features: http://www.treesurgery.com

You will notice that the search function doesn't work. This is because an earlier customised version of the directory plugin (Business Directory Plugin http://businessdirectoryplugin.com/ ) got accidentally overwritten and this has caused a clash with the maps plugin that they also supply

What should (and used to) happen is the following:

1. User enters Postcode abd selects which categories they are interested in and hits 'Search'
2. Page scrolls down to Beneath this search box, where a Google map appears with flags on the map for each search result that has been returned.
3.Beneath the map, all the search results are listed.
4. User can click on the flag for more summary information and then click on through for the full listing.

Example of summary listing here: http://www.treesurgery.com/business-directory-2/treesurgery-category/tree-equipment-hire/

Items no longer appearing in sidebar and they need to.

Individual listings not currently working
Extra services needed: Customization, 3rd party integration
Specific technologies required: javascript, php
