I have seen people suggest 10ish+ snakes to consider breeding feeders.
Everone has different variables that might make them decide to do it with more or less snakes.
Some people do it because they enjoy mice and rats, and want to do it for fun.
Not sure if this is a useful answer lol. If it based on money, just add up your costs for each option and you will know what will work for you. Breeding has initial start up costs but imo pays itself off.
