[Dot Pecson]

One way to get clients who at least know how to read... would be to write articles for your local paper/s.

This would get your name out there as an expert, you'd be informing your public each time your article is published, and you could give your website as the contact.

Make the article timely, of course. And perhaps you could do it once or twice a month? Sort of a Green Corner type of thing that the paper could run?

Also consider press releases. This could announce your company's latest discount [3 for price of 2?] or a new employee [Landscaper teams up with Arborist] or the proper technique for caring for your ____ plants [Nematodes vs. tomatoes].

This could well help you improve your client quality.

PS - You could also distribute flyers offering... a free report on _____ if the recipient would go to your website and request it [this way you get their email and can offer to send them future reports if they click on "agree" or something]
