I'm still not sure how this is economically viable. At the IRS rate of $0.55/mile and the average messenger pay of $12/hour, about four or more deliveries per hour would be needed to break even just for the hour. Add traffic and downtime for when the messenger has no deliveries and it doesn't seem possible.<p>For comparison, in Chicago a company called Dining-in has similar constraints -- delivering within about an hour a custom order. They charge $6.99 -- excluding the tip.
