Eileen's post on offering to cut lawns for free is spot on. Sure you will get some people taking advantage of you but not many. Once they have seen how good a job you do they won't want to go back to cutting their own lawn.

Some complementary ideas:

• Go for a long term deal - lawn cut twice a week in the growing season (whatever that happens to be where you live) for $xx
• Offer a total annual lawn care service (spring weed and feed, all year round cutting, edging twice a year, autumn feeding etc) for an upfront annual fee
• Do the above on contract
• Target a niche - affulent cash rich, time poor.
• Offer a discount for referrals
• Form some joint ventures with lawn care product suppliers: ornaments, furniture, lights, fencing, tree surgeons,....
• Once you have a relationship with a client introduce your JV partners services or products - you take x% of the sale.

Keep thinking, there is a lot you can do with the lawn care business.
