Graphic of a map of the Sutherland Shire showing sales in certain suburbs

We need a Map drawn up of the Sutherland Shire that will show our sales over the past 12 months and where they have come from. This can be shown as a circle (maybe scale of circle indicates the amount of sales). We would need this done is our brand colours. It will need to be over a double page spread as it's going into an A4 booklet
