Copy Google API Map and website integration

I am taking over a website for a customer and I have to copy the existing Google API maps with placemarks and integrate it into the new site. I need someone who has the skills to copy the mapping and create the process for me to be able to add entries easily for the future. Existing site and maps here [login to view URL] You MUST submit a sample map with one of the copied practitioners on when bidding. This is a very simple copying job for someone with Google API maps experience so no silly bids please.
