Do a search on the topic within the forum, you will see it is strongly recommended that you do not attempt this. It is not healthy for your frogs, and takes a lot of expertise. If you need to ask that kind of advice here, you aren't ready for the undertaking.

Next, I highly doubt that any commercial breeder, they will be the only ones with first hand knowledge, will give you information on how they breed their frogs.

Lastly, have you taken into consideration all the logistics of raising, caring for, and selling potentially thousands of baby frogs?
