I would focus on the blue collar world if I was you. I am a new start up and have 3 accounts. 2 of which are with trucking companies and the 3rd a construction supply company. They are far less picky and demanding then the white collar world. I have also noticed that banks, call centers, franchises (national chains) tend to already have contracts with national cleaning companies that they cant veer from even if they wanted to. Although this is not always true I think you will get more play with smaller blue collar type places. My 1 contract never had a cleaning company and I actually sold them on the idea. Also please take note. CAR MAGNETS. Big as you can get them with a catchy phrase, logo and attractive coloring. Make sure you keep your car clean to because its bad advertising otherwise. Also most people just put them on the sides, which is not well thought out. You need something on your hood and your rear end as well. Its about the cheapest and most effective way to advertise. Make sure that when you go about your daily business (grocery shopping, out to eat, movies...) that you park away from cars but in a visual place. Also when you are home park at the end of the driveway or at a good angle. Good luck.
