Looking for some RTB female dragons

My 13 year old is wanting to get into breeding bearded dragons. He spent the summer mowing lawns and helping out the neighborhood and earned enough money to get together a couple of 55 gallon tanks, a incubator & appropriate lighting substrate hides ect. .

So far he has spent about 600$ of his savings, He picked up a citrus/paradox male & is looking for a couple females to start doing beginner projects with. Long story short If anyone has anything that would work. Let me know! (He's only got about 2-300$ left to work with!)

Thanks
