For MOST of you... MOST of your business does (and should) come from the people you know and/or have served before. THIS IS YOUR MOST PROFITABLE BUSINESS SOURCE. Not to mention it's so much easier work than finding someone new to convince to trust you cold.
Contact every past client and say 'hello'. (LOOK! Another way to pick up that phone!!) ASK them how they are and what's going on in their lives. LET THEM TALK.
Tell them they are important to you and that you are here to help them whenever they need you. Tell them that you are going to be around a LONG time so you'll be there when they do need you in the future.
Come from a spirit of contribution. Care about the conversation.
Follow up each call with a thank you note and 3 business cards.
I can ALMOST GUARANTEE you will get a lead from this today or in the near future.
PS - Want to PLUS this exercise? Schedule the next contact with each person in your database. Do this until you get through them all. Or at least for 28 minutes today :)
