Need help bidding on an initial/deep commercial clean
I used to do vacation rentals and residences. I have recently gotten a couple of post construction jobs and now I am bidding on a 2500 sq ft. office building that also used to be a barn way back when...it's extremely dusty and hasn't been cleaned good in over a year. There are 5 offices, 2 reception desks, 2 bathrooms, & one "kitchen" with a fridge, microwave, & toaster oven. There is also a fax/copier room, two meeting areas with tables, two fireplaces & a storage area with shelves & all of their marketing materials. It's all hardwood floor except two small areas. This place is a real estate development office so it needs to be really spic & span. I'm having trouble coming up with a number for my bid. The people that did do it over a year ago charged $400 but it seems low for everything to be done...
