Well, if I get 100 people to use. (Not at srl, as I have decided for now srl gets free.) The service = $3 a month, minus paypal tax. Thats about $240 a month I make. Thats just an extra $2,880 a year. But if I advertise right I could get potentially more customers.
And I don't go to college for a couple years. This would pay for about half a years tuition.
