You got very lucky in the onset of hiring someone. Usually, my boss runs thru 20 people to get a keeper.
I do recommend that book quite a bit. And while I don't have any successful business advice I do know this....
Expect to make very little off of your employees. Like maybe 2 bucks an hour. My boss is right at 50 employees, so he might might make a 100 dollars an hour.
Of course he says it takes 1500 an hour to keep the doors open. (But this is a larger flooring company).
Good luck.
