When you’re working, make sure your vehicle/clothing clearly has your name + contact info.

After you’re done working, go door-to-door and distribute flyers on the same block (your neighbor at 123 Main Street is using us, and we’d love to have you as a client…)

Target new home owners. Welcome them and give them a gift of a free consultation, etc.

Talk to existing lawn people. Perhaps they have too much work or there are jobs they don’t want and would be happy to pass along to you.

Talk to your local garden center. See if there’s a referral board there.

Hold a free class on “How to Make Your Lawn Easier To Care For” (for example). Really give value. The point is that you’ll position yourself as an expert in their eyes.
