It has to be good service, of good quality
or else they won't pay as much. Sure I could hire a High School or College graduate and pay them $5.50/hr and only charge $12/hr for services and pocket the rest. I can garnendamntee the service won't be the best quality and the PFY will have to return to correct the mistakes he/she made. I'd rather hire an expert like deSitter and pay him more and make sure it is done right and of good quality. This alone is worth the extra money. After all, how much is downtime worth to you when the PFY messes up and leaves the client hanging?
