Create 280 maps in google maps from GPS data

We have the GPS coordinates of about 4500 outlets in Excel. The outlets are divided into 280 areas. What you want the freelancer to do is to create 280 maps in Google maps, each map will show the outlets which are in that particular area. The successful freelancer will be very familiar with Google maps and will be able to do this task relatively quickly using automation and importing.

Furthermore we want different types of outlets colour-coded as per the colour code key attached.

Attachments for the project are:

1. list of areas

2. format in which the corners will be provided

3. list of the colour codes for the different outlets
