As for ( what do you pay a cleaning person)
Some have set rates, some are open to negotiations, when interviewing that needs to be discussed. First ( maybe ask friends who have them what they pay)
Decide what you are comfortable with, can afford. As with everything different areas have different rates ( some places people pay $2000 a month rent, some places $300 is a norm)
So, location matters. We started paying ours $20 an hour - now we pay her $60 every 2 weeks, it doesn't matter if it takes her
1 1/2 hours or 4 hours, she gets the $60. ( most of the time it takes her about 2 1/2 hours - but I don't feel bad if once in a while I ask her to do something extra, not a normal task & she doesn't mind doing the extra once in a while. It is important to have good open conversation with your help. Call a couple ( services) & ask what they charge to also get an idea but remember, they will be higher than private hiring, you are paying for the administration too- if they charge you $35 an hour the person they send may only be getting $18 an hour. I know one agency who charges $30 an hour and pays their help $8.25 ....
