If you are really busy and finding it difficult to keep up, it might be time for you to get an assistant.
Remember, an assistant can be a high schooler who's willing to work 10 hours a week for you for $7 an hour.
That's less than the earnings of one party, and let's be frank here.
If you cannot generate one party from 10 hours of phone work, answering this challenge would obviously be a waste of time! LOL!
See? You could probably generate a full month's worth of bookings in 10 hours, and easily pay for some help with organization.
