Assorted virtual help for an entrepreneur with multiple small businesses

Help! I'm overworked and need help performing tasks such as market research, data entry, phone calling, order processing, thinking through business problems, building presentations and spreadsheets, etc. This job will not be tedious, you will be called upon to do whatever it is that I dont have time to do, but needs doing. I have businesses focused on Mixed Martial Arts business services, printing (on just about everything except paper), hospitality and building some based on education, safety and electronic identification and personal data storage.
