Well that's an interesting position to be in. I can tell you one thing, I've ran a number of businesses in my lifetime, and I can say, there were multiple nights I went without sleep to get the job done. Some were $4000, some were $200, but I did what I had to.
Faced with losing an hour or two of sleep, or losing a potential sale, I can honestly say I would take the former and that isn't a snap judgment, it's based on experience

. In fact, we've all faced that type of situation from time to time.
Sure as my success continued I could be more picky about the jobs I selected, but man, no matter HOW well I did, I never got a $4000 offer for less than one day of work (let alone a couple of hours). But I can assure you, it wouldn't have been turned down

.
