I had an low income apt. complex owner call me today asking for a bid on cleaning heir gutters out twice a year. The buildings are a total of 588 lin. ft. spread out along 7 buildings. They are roughly 22 ft up with a very low pitch roof so you can easily walk on them. They have no trees around but still want them blown out occasionally. If I were to charge .75 per ft it would be $441. Is this to extreme? Please let me know. They also have another complex with roughly 1200 lin ft two blocks away. Please let me know your input.
