I had a phone call today from the New Look shop in our local town to come in and give them a quote tomorrow. now as this my first commercial call I thought id ask you guys first. do you charge more for commercials because they can probably afford it, or quote lower on the basis that they will get quotes from a few windys and pick the lowest? they want it done fortnightly, its a pretty small shop, two windows at the front measuring 2 x 1.5m each max. and a double door inbetween the windows. im thinking about 12 to 15 quid fortnightly? or am I way off the mark for that?
