I'm not saying that you shouldn't do it but you have to understand that it's not quite that easy to do. There is more to running this kind of business than just getting the leads and getting subs to do the work.
For instance, if a sub screws up a job and you have no idea what they did/didn't do, you would have a very hard time trying to force them to do their job "correctly". They can say that the system works, the customer can say that it doesn't and you'll have a hard time trying to determine if your sub is a hack or if your customer is just crazy.
Or if your sub tells you that a system needs a $400 part when it doesn't, he will start to take advantage of you and your customers and rob both of you blind. Maybe your subs are honest and ethical which would be great. But it's not unlikely that they'll have you spending extra money that you don't need to spend even if they are honest.
