Three nights per week cleaning

I have an office that needs to be cleaned with a key provided so you can go anytime after closing you wish. Tuesday nights, Thursday nights, and either Friday night or anytime over the weekend . Tuesday and Thursday nights after 7 PM two hours each night as long as the cleaning is completed before 6 AM in the morning and then the weekend is anytime for four hours. Clean BCI only no 1099 company check only no cash. Residential or commercial cleaning experience only.
