A couple of thoughts:
1) Start with quality stock, whatever you keep. Dave's Rare Fish (www.davesfish.com) is a great supporter of the Capital Cichlid Association (www.capitalcichlids.org) and is my go to for Rift Lake Fish. Or if I get fish from club members, I prefer to get fish that have come from Dave or another trusted source.
2) I'd go with one species / variant of peacock or similar. Choose something that you like and want to work with. Breeding mouthbrooders is nearly always easier and better with a large harem. Depending on the species, 12-25 fish will fit nicely in a 55g that gets regular water changes. A couple of males and a bunch of females is what you want.
3) Be prepared to raise the fry: You'll need grow out tanks and tanks for holding (and recovering) females. No one wants stunted, poorly raised fry and most people will want "the largest, most colored-up male" that you can sell them.
Another direction which could work (although a 75g would be better) would be Tropheus. You need a big group.
