Heres how I do it: My loyal, long-time customers bring me a new account (that meets my criteria...(in my area of operation, desires weekly service, not a gnarly rock-strewn moonscape, not a grumpy 'ol PITA owner, ect...) and I go and check it out. Yes, my referral-base has been trained as to what kind of clients I'm looking for...and they don't bring me any crapola situations. If 'the deal' goes through then the referring customer gets their lawn mowed free the next time. Most of my customer's lawns can be done in 1 hour or less...a small price to pay for a new weekly client, IMHO. I'm practically booked for the season now (they know this too)....so they better get it while it's still available. Good luck with the upcoming season, mower_babe!
