Landscaping xxxxxx county - think of keywords and the url http://www.LandscapingMartinCounty.com
or LandscapeDesignPalmCityFL.com so the name of the company would be Landscape Design Palm City FL, Inc.
No one is ever going to put in google Green Image if they were looking for a landscaper in your county unless they know about you. Your Description and keywords are going to have to pull in the Landscaper and servicing area.
Not to confuse you. The Name of the company could be Green Image Landscaping, Inc. and the url could be still be the http://www.LandscapingMartinCounty.com
Speak to someone who does marketing before you pick a business name. Hopefully it will be with you a long time.
