Also, real estate agents throw your business cards in the trash… unless they are attached to this: http://www.nachi.org/magic-marker-marketing.htm
How to book ?
If they called they are considered booked already 
i use the book, and that works, I’ve not yet tried the magic marker use
Your former clients can’t remember your name (to refer you to their friends, neighbors, co-workers and relatives) and they threw your inspection business card in the trash not long after you did their inspection. The book is what keeps your business cards alive and working for you for years to come. Americans don’t throw out books, they throw out business cards. Attach the latter to the former.
You should have lots of these books out there in your local market working for you 24/7.
