Mac,
Our marketing has always been basic, yet very good for us. I have read allot of threads on this subject and opinions vary widely depending on location, specialty, existing cust base, ect..
If we are looking for new lawn maintenance accounts, we use brochures on mailbox's on the first good weather weekend of the late winter/early spring. For high end landscape/hardscape jobs, we do direct mail (post card) marketing to recent home buyers. Interent is good for all categories so a good web site to show off your work is key.
You've peaked my interest with your "offer" idea. I've seen allot of landscapers do allot of different "gimmics" ,and I'm not implying that yours is a gimmick but, I have found the best special "offer" you can have is reliability, reasonable price, and good work. Sounds old and broken but it's true.
I have written many marketing plans over the years and the key to a good plan is flexibilty. Most landscapers are balls to the walls in the early and late spring. My point is, if you have something printed, try your best to keep it generic as far as timing goes. No specials with dates. This way, you'll be able to re-use the brochure/flyer another time of year when you need it.
