How much should I charge on the work that I done on cleaning a new addition of a church?

Question

I cleaned a 6000 sqft addition. The walls were finished and ready for painting but the 2 story addition had no circulation so the dust stuck to walls. I had to go thru and wipe all the walls down. Even the elevator shoot. Then I had to clean 24 windows inside and out that were solid glass they were about 2' wide by 6' tall. Down stairs floor was concrete that had saw dust and alot of sheetrock dust and mud and had to sweep and scrub up all dust and mud mad the floor smooth. Upstairs there were 4 rooms and I swept all of them and two long hallways and done the stairs ( scraped the mud up and swept) I am not sure what to charge and they are waiting on me to send a bill.

Answer 1
