I installed Google Maps on my own website today just to try it out. It’s fairly simple and Google provides a lot of examples on how to do it.
1. API Key
First you have to sign up for an API key – a Google account is required. This key can only be used per domain and has to be used in the Javascript code to verify ownership.
2. The “Hello, World” of Google Maps
Next, create a new file on your server and copy and paste this code into that page. Make sure to use your API key.
3. Test your page on your server.

If you don’t have time to figure it out I can install it for you for a minimal fee.
