When your business first started, you probably did most of the "donkey work" yourself. Remember all of them proposals you drew up? Remember dropping them flyers around your local neighborhood? These jobs are probably not worth as much time as your duties today are. You will find your time is better spent interviewing new staff, meeting potential customers and keeping up relations with current customers.
With the aids you have at your fingertips, these smaller jobs you once did when you first started are easily completed - and for reasonable prices. Utilize the tools you have. Offer reliable workers in your local community some work. Or search the Internet - there are many people looking to do odd jobs for small fees! Prioritize and be prepared to invest a little now and again.
