Sounds like you're on the right track. When it comes to advertising, even if you're not planning on having a web site, create Google/Yahoo/Bing local pages for your business as soon as possible and that will help market to those who sit in offices all day searching for services on their boss' dime. lol Well thought out Craig's List ads (read: not all caps, not a string of exclamation points, and a professional image portrayed) can also be very effective.
I know lawn & landscape marketing, branding, and web strategy. I'm not anonymous, I just don't self-promote.
