Need help creating a graph

Should be quite easy, I am looking for someone to create a graph for me that depicts how a venue would grow from placing an ATM at their business. Venue has about 1250 guests there a week, about 120-156 people would need to use that ATM with a fee of  $2.50 per transaction. Can anyone represent this in a graph for me that would show the monthly revenue for 24 months.
