Healthy food for hackers. Increases happyness+productivity and is a surprisingly big buzz these days with books on the topic and whatnot.

Basically the value you want to provide to startups is that they can use your excellent food as marketing for new employees.

Research customer support ticket software and maybe offer on demand food. Turn those late night hacking sessions on pizza into late night hacking sessions with fresh food (or maybe even a chef right there to cook)

And yes door to door sales ASAP
