Dale has an idea for software and would like to hire a programmer. Leo says that's how Facebook was created, and the risk is, that he could get ripped off by an ambitious programmer who decides to do it himself. So he should make sure he has an ironclad contract to protect his IP. There's also the risk that he could spend a lot of money and the programmer just doesn't deliver. In the end, a brilliant idea isn't what makes money. It's the implementation. The safest way to do it is to learn to do it himself.
UpWork is a source for hiring programmers though.
