For starters, Market Force does food delivery shops with a major American burger chain. Intellishop does food delivery shops for a startup linked to a celebrity rapper but I don't think they have a location in San Diego.
The delivery shops I have done using delivery services have been for the restaurant itself, not for the delivery service. I have not tried the celebrity rapper shops as the guidelines I can see do not seem clear and the prices are quite high for one pizza from the shop near me.
