We've had to seriously diversify. I went and got a general contractor's license which allows us to stump grind, repair decks, etc. in addition to the usual commercial and residential maintenance. I think this has been the reason we've kept busy. All of my weekly maintenance contracts are winding down with the last of the leaf/Fall cleanups. I've only lost a few of my regulars due to lowballers. I've actually fired more customers this last year then have lost to the cheap guys. I dropped all my print advertising (too expensive) but use Google Adwords to drive customers to my website. I've cultivated a good list of subs for tree, concrete, irrigation, and low voltage electrical work and can effectively bid the jobs out.
One thing I don't do is underbid. Not for maintenance. Not for repairs and especially not for the stuff that requires other licensed specialists. It just ain't worth it. You're better off staying home and watching Netflix....at lest then you won't be out losing money.
We're running two trucks with trailers now and a motorcycle with a milkcrate bungee'd to the back this year.
I always wave to the other lawnguys.
