Its far more complicated than that, especially the aestivation period or "cycling." You also have to consider light cycles, temperature cycles, cooling and warming cycles, feeding cycles, sexing the frogs, identifying readiness to breed in females, constructing a proper rain chamber. Then you have water chemistry, feeding tadpoles, housing hundreds and hundreds of frogs, preventing cannibalism, and then finally selling the actual frogs.

You have an Ornate Horned Frog there, which are more difficult to breed.
