You’d do most of your work in a home garden, but you’ll have to spend your weekends away from home. If you love the idea of selling your home-grown produce, but can’t swing being out of the house on weekends, consider selling to friends, family, and neighbors instead. Almost everyone prefers the taste of a fresh picked tomato to a store bought one.

Samples. You’ll need some samples before you can really begin marketing yourself. Figure out which market you want to approach first, and then find or create some related samples. For instance, if you want to try your hand at blogging, study some successful blogs, and then write a few posts of your own to use as samples. Do this for any and every market you’d want to write for.
