They did a great job - mostly took care of assembling materials themselves, and - after a quick demonstration - they did all of the work themselves. I had 'hired' Daniel for the job, and told him I'd pay him $30. When he enlisted the help of his siblings, I told him that he would make the decision about their pay.
He decided they each earned $10. Pretty fair, I thought. Of course, the extra twenty came out of MY pocket - not his!
They worked hard and the deck ended up looking terrific.
