Those are the only specific people I knew who might have them - have you tried posting on craigslist? I'm sure there will be someone with them in your area if you ask. Also you could order hatching eggs and hatch your own if it came down to it.
As far as I know they sell coturnix, not sure if they sell babies but you can always ask. Here's their facebook, not sure if they have quail available now but they only take 18 days to hatch so you could always see if they're willing to hatch some for you...
Depends on where in NY. I know a local farm in my area that raises and sells them and would probably sell you four. Have you also checked and posted on craigslist?
