I would not be too surprised. Some guys are very good at keeping their expenses very low and bringing in the business. Its a lot easier to make money when there is just the two of you. No worrying about unions, workman's comp, health insurance, and all the other things that suck the life out of other businesses.
I knew a fellow that had two guys working with him. They rebuilt old industrial furnaces. I don't know how much he made, but I know that he wrote each of the two guys who worked with him a check for $10-15 thousand each quarter as their share of the profits. And that was on top of them getting a draw of $2000 a month against the profits. If you think about it, even if it was only $10k a quarter, thats a net of $64,000 each AFTER taxes.
These guys did not splurge on anything. They worked as hard as they had to and made good money at it.
No reason an EC who was really astute could not make really good money too.
