I don't believe Pro Exotics does yellow ackies anymore. I know they do red ackies, and I believe they actually have some available now. (or did not too long ago.) I did acquire a yellow ackie from an Eric Burruse, and it was a semi-painful experience, so I wouldn't recommend him if he crosses your path as far as options go. Hopefully some others can give you positive recommendations. I just had to pass on a warning.
