Good evening family I'm have a mobile commercial fleet cleaning company. We only clean semi trucks but i been in business for 4yrs now, I grow my business off cold calling and doing washouts all year around. Now a few of my biggest clients departed from us and now I'm running around crazy cold calling getting 20 and 30 NOs. What is another method I can use to get more commercial clients, it seems so hard to get FedEx, Amazon, and other large fleets and advice will be appreciated thanks...
