-keep in mind the demand for those fish is relatively low, and i can tell you from plenty of personal experience there is not really any true "profit" to be made in it. you may be able to essentially cover the costs of feeding/housing/capturing the fish, but that's about it. the amount of time that goes into rearing/maintaining juveniles (even for just transport) or shipping adults is quite large, and the returns are break-even at best.
if you're doing it to get some spots into the hobby that's great, but i wouldn't recommend doing it to make any money. even with Cubans we basically break even on costs of feed/housing--
