…just sat down at the nearest table and finished eating what the customer before you left on his or her plate?

I’m writing a business proposal for a place I’m interning at, and that is to be reviewed by a professor. It’s basically regarding a free online database for alternative and/or medicine. In order for it to be free, we need to make money off of advertisers. Who would be good businesses to talk to about paying to advertise on our website?
There is a few criteria:
1. They should be small local businesses that generally cater to sustainable living, such as fair trade products, hand-made crafts, family-owned restaurants, and food co-ops.
2. If they are big business ideas, then they should hopefully be somewhat in sync with the basic philosophy of economic equity and sustainability. We want more than anything to help promote small businesses, especially during these economic times, but it wouldn’t hurt to have a few large ones on there too.
We also would like any advertisers to be unconnected with pharmaceutical companies, if possible.

Just respond to this question with ideas, or shoot me an email if you have further questions or wish to share information that you don’t want posted on here.
Sorry, I meant it’s a “free online database for alternative and/or HOLISTIC medicine.”
