They are everywhere around here. It's nice to see another parrot lover I just rescued a little one who's marbled black (for now) and only has one eye. Have you found any on line?
The small unpeeled ones at pet smart are almost always yellow or domino parrots.
You can get them for around eight bucks a piece, buy 2 or 3 watch them peel and keep the best one. You don't see yellow ones commonly because they are considered low grade, purple which is a deep red is the highest grade.
