They are small labels, can't confirm if they're LA or not. Both are impossible to find. They are available as downloads if you look in the right places. I would recommend downloading both before you seek out vinyl. You will have a long wait, and they'll cost you.
In the mean time, how about spinning "Jazz Heat, Bongo Beat," one of my favorite LPs from the Crown label, featuring Buddy Collette and the Latin Jazz All Stars?
