Heather, you will find, this is a hard way to make any profit. for me, here in the nw, I have spent more in postage trying to acquire and propagate these special plants, only to a year later find out that if I had put that money towards buying the trees, I should have fruits by now... instead... hum, it is a hobby that I cannot afford. It is fun, however. In California, you have your sunny weather to your advantage... if you work hard, anything it is possible. All the cuttings I sent to my Cal. friends have taken roots and even fruits. Also, there are so many trees locally, you should not have difficulties getting cuttings locally.
I wish you all the luck with your journey.
