Diya! were you thinking that all users are from DC and surrounding area only (since you did not include your area at the first go)?

Diya! ( I like your name) do you personally deliver the food?

Oh yeah, don't forget to charge that gasoline surcharge based on delivery distance else it might bite into your profit.
Also pay attention to the health code. After all, we are in a nation of lawyers.

All the best now.
