Bruce, where are you located? Depending on where you live, you might already have truffles nearby. For example, I live in Oregon and Oregon white truffles are found here under Douglas-fir, including my food forest farm.
If people are sincerely interested in growing truffles and are not into a get-rich-quick scheme, I always suggest that they check out Taming the Truffle, a book by Ian Hall, Gordon Brown and Alessandra Zambonelli. This is one of the best books ever written about truffles and truffle growing. Site selection, changing the soil pH, and finding the right tree and truffle species for your area are all crucial to success. Territorial Seed Company also now sells truffle- inoculated trees for those who wish to try growing European truffles.
