How much would you charge?

So currently out of work with the corona virus, and my son's dad offered for me to clean his house and pay me. But how much would y'all charge. Its 4 bedrooms, 2 and a half baths. He wants floors, Windows, bathrooms and the counters and appliances done. Its roughly 2500 sq feet. I have no clue what to charge him. He doesnt pay child supporty because we do 50/50, and I just dont see the point if he has our son just as much as I do. He makes 6 figures, where im a server at my family's bar\ restaurant. So I dont wanna low ball myself but I also dont wanna ask for to much. Thanks for any ideas.
