Ghost shrimp while, freshwater as an adult, need brackish water to breed hatch and grow while in larval stage. Prolly to labor intensive.
Brine shrimp are saltwater. Hatching brine shrimp from eggs to use as feeders for fish fry is common. You should be able to find DIY setups on the forums here or elsewhere online. I wouldn't know about growing those baby brine shrimp to a bigger size though. They die relatively shortly afterwards when introduce to freshwater to feed.
Red Cherry shrimp breed rather prolifically in small freshwater setups and can be used as feeders, however its typically more efficient to just sell the new cherry shrimp you breed and use the money to buy whatever feeders. You could prolly breed the wild variant of the cherry shrimp which is not red, and use those to feed.
In the long run using processed foods is the best option cost wise.
Hope that helps a little.
