Recommended reading for future market gardeners?

I'm looking for books or website/other resources for me to read - I would like to start market gardening in about 5 years, right now I don't have the time but I'm just testing out varieties and growing for our family. Are there any good market gardening 101 books around? I'm particularly interested in the business side of it, I have a degree in business but my impression is that the market for this sort of thing is really different...
