I think that pine trees have to be grown from seed but yeah, pay attention to what's been posted above, get some good books, do some research on line and good luck.
Regarding the fruit trees it's really important to do as Live_Oak mentioned. Lots of people have planted fruit trees from seeds they got from a fruit they liked and have been very disappointed. If you go to a nursery it's easy to see where the scion (the top part) is grafted to the root stock. For some fruit trees, like apples and citrus, one can graft a bunch of different scions onto one root stock. We have a 4 in one apple tree that's that way.
Maybe you can develop a niche market; one nice thing about growing is the sunlight's free and the water, depending on where one is, is cheap.
