My ex boss charged $33 an hour in Melbourne but she could really ask for that, she did a freaking fantastic job! Every client she stopped cleaning for would be replaced by 3 more. Business was good. She assessed per hour rather than per house. Clients supplied own cleaning products, vacuum cleaner. We supplied mop and rags unless the client wanted it steam mopped then we asked them to supply that. If your sister uses enjo then you wouldn't have to worry about rags.
