Congrats on the first phone inquiry! Good luck with that! And glad I could offer some help.
One thing too... don't be afraid to say "OBO" or "OBRO". You might get some low-ball offers, but you can always refuse those. But including that in the ad, you might get some people more willing to try you out if they know they might be able to haggle a little. I personally am not a big hagglers when it comes to animals (I can and do haggle for inanimate objects though!), but I know other people may be.
One nice thing about craigslist too... when you use the search function for your immediate area, it will also search ads just outside your immediate area. I'm in the Inland Empire, but when I start searching for things, I'll also get hits for Los Angeles or San Diego. That's nice for people who are willing to travel (and let's be real, a lot of So Cal residents aren't afraid to drive a little bit for something they want, since our world seems to be centered around that!), and gets you a little bit more potential business/views.
