I'm starting in on #7 soon.
I really enjoy it, but I'm a hands on kind of guy and I'm not the boss for once. You will meet many interesting people and some will become friends and customers.
I usually can show up with 3 trucks, 6-10 talented people and professional tools. The paper always does a piece (free advertising if your trucks make the photos) and it's a tax deduction. You will be working with bankers, attorneys, grandmoms, the new home owners, you name it but the atmosphere is all positive. Someone is getting a new home who couldn't otherwise afford it.
Try it, I think you'll like it. If you don't, nobody will say anything if you leave.
