I need help with a commercial cleaning bid. The apartments are off campus for a large university. There are 64 apts with 4 bdrms and 4 and 1/2 baths in each unit along with kitchen, living room, and dining. They will all be cleaned within a 9 day period. Also keep in mind they were lived in by college students. If someone can help me come up with a reasonable bid that would be great. Thanks to anyone who can help me.
