You might try getting in contact with The Green Store on Mollala Avenue in Oregon City. I think her name is Gwen, the owner, and she could give you some great help and direction. They have a organic groceries, vegetables, meats and coffee, and many, many local jams, jelies, candles, etc that are organic and were made by and from local organic farms. It is a fairly new store, and they plan to have cooking and saving classes in what used to be the house's garage sometime this summer.
I think they only reason those people living in the arage are moving out, is because they're planning on putting in a professional kitcken -cooking, freesing and keeping classes will be held there.
Gwen will be alble to give you some good insight, since she's so connected with local farmers, and all the regulations. Very smart lady...her home was situated on commercial property, as well, and they turn it into this very lovely, local organic store. So, I'm sure she knows the ropes.
But what kind of business are you going to open up? I just assumed it would be food!!!
