1. Open Google My Maps in your web browser
2. Click on the "New" button and select "Map" as the type of map you want to create
3. Enter the location for the emergency plumber service, such as a suburb or city in Melbourne
4. Click on the "Add marker" icon and select the circle shape tool (or rectangle if you prefer)
5. Click on the "Edit" menu and select "Marker properties" from the drop-down list
6. Set the following properties: - Name: Give your emergency plumber service a name, such as "Emergency Plumbers Melbourne" - Phone number: Enter the phone number of the emergency plumber service - Location: Select the suburb or city in Melbourne where the service is located
7. Click on the "Add service" button to add the emergency plumber service to your map

To complete the process, click on the "Share" button and select "Map" from the drop-down list. This will open a new window where you can enter a title for your map and copy the link to share with others.

Once you've created your custom map, you can use it to raise awareness about emergency plumbers in Melbourne-based locations, or to promote local businesses that offer these services.
