I have been doing primarily residential jobs for the 2 seasons I've been in business. I get my customers from a variety of methods including 'pull tabs", fliers, craigs list and newspapers. My most productive has been fliers and pull tabs . My signs on my truck doors have only gotten me minimal results. My question is about moving into more commercial work. How do I find business' who need my services? Do I just "cold call' on desired places ? I'd like some tips if you have any. Thanks Your Neighbor Tim.
