Farmers Market

In the near future I would like to start making my own burdock tea, peanut butter, and vanilla extract. The problems that I am having is that I don't know where I can buy burdock root, peanuts and vanilla bean pods in bulk.

I'd love get as much of my produce from a farmers market. However, I'm new to Vermont & I don't know where to go to get the local fares. 

I'm also hoping that I will be able to find some bees wax for my beauty products before summer.

I'd appreciate any feedback that would help out.
