Any reptile shop will be able to get you one in no hassle.. bad time of year but even so, they are out there.
However since you have posted this in the DWA section I am gong to recommend you dont buy one.. they are not DWA animals and you should really have known this before you even looked at sourcing one.
I have kept lots of falsies, they are indeed my "pet" species, I adore them and have spent a good deal of my time studying them. Whilst Mason claims most are very forgiving this is only true of CB animals and even then only those who have had confident, consistent handling.
They are very fast and their feeding response is outrageous! Some of mine have just sat with their mouths open waiting for food whilst others will literally leap from the viv when they smell dinner defrosting. They dont care what they hit either.. their aim is poor and hands are fair game.
Their nasty reputation is admittedly not entirely deserved as most tame easily with handling, but there are plenty of adults out there that are not tame and will not settle well.
Almost all are also viv territorial to some degree, not a problem for someone who has kept a few snappy snakes (indeed even a few stressy kingsnakes!) but for someone with a hoggy, corn and rainbow boa.. well.. make sure you buy yourself a youngster. Those "grow into" their attitude a little and then settle, whereas poorly handled adults are never trustworthy, even once "tamed down".
