Small Business Advertising Advise?

I'm going to do a target area mail out to advertise my new business and wanted some feed back on what is better.
Is a one page flyer outlining prices, services, contact info, etc or a tri-fold brochure with more detail the way to go?
It's going to be a landscaping business so wondering if people would take the time to read a brochure where a flyer is simple/ to the point?
