Welcome. You may take some flack for asking for handouts with your first post ;) , but offering shipping is a smart way to do it! It never hurts to ask, and I'm willing to bet someone will hook you up. If not, lots of folks sell cuttings for cheap, and many sellers have a knack for including some extra varieties, especially if they know you're new. Lots of good folks on the forums.
In the meantime, do we have a name to go by? I'm Brett, and I've been at it for a few years now myself. You're spot on about it being addictive, but you're lucky...out in AZ, you can grow most things in ground. Good luck!
