I was being facetious.
Ya need to re-figure how you communicate with your customers. Regardless of how many people you take, your first hour will be XX amount of dollars, based upon what truck you take, what equipment and whatnot. After that the hourly rate will reduce a little bit. Now, let's suppose you have another person working for you. What would you charge for his/her hourly work IN the shop ?? $60 ?? Well then, you need to charge maybe $75 or $90 an hour for his time outta the shop and on site. His/her workmenscomp will now be different, not to mention you can get more done in a familiar environment, than you can 15 miles away from your shop in someone else's place. So, by raising your initial hourly rate and adding all the necessary people with proper overhead included, many time installations cost more than the frickin' signs. Don't forget, you need to add in permit costs, obtaining those permits and engineer drawings if necessary.
