Client filter process

In a recent “Double your Business in 3 Months” call, Brooke talked about how she used to (when her business was much smaller) get on the phone with potential clients for her certification class and would discover that they just wanted to talk to her and really didn’t have the money for certification. Brooke then said that she developed “a better filter process which narrowed my niche down of people that actually got on the phone with me.” I sell a high-end service and I am great at providing value in an initial complimentary call, AND I would love to hear more about the “filter process” that Brooke used with certification. Thank you for your time.
