Embedding google maps on my site

I run a site at http://www.yellowweddings.co.uk. It is a directory of UK wedding suppliers. When an advert is shown I wish a google map to be shown with the advert using the address of the advertiser. The address is 'pulled' from a mysql database. ## Deliverables My site is at [login to view URL] It uses 68Classifieds software as the base code for the site. The site is a directory of wedding suppliers in the UK I require....... Currently when an advert is displayed on the site the name, address and company details are shown I wish to also display a location map of the supplier under the advert. The UK address is shown on the advert - I wish to use this information to place a marker on the map. I would suggest using Google Maps API to do this. The address data needs to be read from the application and used (via 'geocoding' ) to display a marker on a map. The map needs to be displayed in an attractive manner underneath the exisitng advert. I can provide access to all existing source code and access via ftp to my server. The exisiting application uses a mysql database, php and smarty Please note. This application uses UK addresses and postcodes. Geocoding UK addresses is NOT as simple as US ZIP codes.
