I've had a fairly good amount of success with residental landscape customers (about 95% of my business). I'd like to know if anyone has some ideas as to how you go about landing some bigger, commercial customers. I've thought of sending out letters introducing my Co. and then following up with a phone call within 10 days. I just really don't know where to start. All of my residential is built on referrals from existing customers. If anyone can help I'd greatly appreciate the advice.
