@squabcurious try the Chinese community
They love eating squab. Try Chinese grocery stores. I haven't checked but T&T Supermarket has fresh squab for sale on their website.

I don't think the average person will want to pay $48 for a squab considering how much meat there is on a squab so you should focus on Chinese fine dining restaurants. Also, try looking for websites for Chinese chefs and "foodie" sites they may know where the farms are. Good luck!
