Welcome to the forum. The CCA is a Washington DC based fish club, so there likely aren't any members in your neck of the woods.
If you are looking for wild caught amphilophus, I'd start with Jeff Rapps at Tangled Up In Cichlids. He currently has w/c and F1 labiatus available. He had citrenellums available earlier this year.
You can also check with Dan at Cichlids of the Americas. He gets in w/c stuff from time to time.
Good luck on the search for flaveolus. I haven't seen them available any where for years.
