Have to agree with duanes; unless you are shipping the fish it's going to be impossible to sell more than one spawn of a cichlid. I've been breeding cichlids and various other species for years, and have had good relationships with LFS's where they would buy fry from me. They will only pay small amounts for the fry; by the time you pay for the electricity to run the tanks you'll need to raise the fry, you are losing money whichever way you cut it. Unless you run an operation like Rapps or CoA, where you have many different species available, have a well-known reputation, and can sell to people in markets all over the country, you will always be losing money.
My advice would be to keep what you want for the pure enjoyment of it, and don't worry about selling the offspring.
Or-
If you want to make even a small amount of money, a much better operation would be to set up a bunch of 5 gallon tanks and breed different colors of neocaridina shrimp. They are very trendy right now and there is demand for them, and LFS's sell them for high prices of 5-15$ per shrimp. These things are incredibly easy to breed, and the market for them is there. I used to breed goldenback yellow shrimp and sell them for 1-2$ each to my LFS when they reached about 1/2". I actually made back the money used to set up the tank and then some over time. I think if you had like 5-10 small tanks set up cheap as possible and dedicated to this, you could actually make some decent pocket change.
