Yep, and I don't think I could ever turn back since I've had one. It took us awhile to find someone really good, but now that we've got her I'm never going to let you go.
She comes every fortnight and does 3.5 hours and we pay her $70. We were paying her $60 and she was only meant to be doing 3 hours but was always staying longer so I just started giving her more money. She basically does everything, dusts (including my venetians), cleans, vaccums, mops etc. I usually give the living area a quick vaccum the week that she's not here cos it does get a little grimy in between, but that's all that I do these days.
Mind you, it took us a long time to find someone good. We started off with a guy who had his own business and were paying him $80 for three hours, but he was a terrible duster and I hate dust. Then we got another woman who had her own business, she wanted to charge $125 but we talked her down to $100. She came once and then left after 2 hours cos her parking was running out (why she couldn't move her car), so we never had her back. And then we found the fabulous lady we have now!
If you're looking for someone I think it is best to go by word of mouth, at least that's what I've found. At the end of the day I see it that you are buying time. When DH and I were both working full time the cleaning took a big chunk of our weekend, we decided that it was worth paying for so that we could have that half a day iykwim? Since we've had DS money is a bit tighter, but we're not willing to risk loosing a wonder woman just so we can save a few bucks for a few months iykwim?
