Because you want to grow then sell, I suggest you contact your county's Extension Service office. They should know of an Extension Agent who can help you.

You need lots of information, even before you plant, beginning with "are local soils suitable for commercial orchards."

Thanks for your encouragement. Unfortunately, I live in a rural community that has a very young, new extension officer who often calls ME for answers! (smile) I will continue to do some research in hopes of attaining answers in time to plant this fall. Thanks again
