I tried to bring up the subject with DH and he is a flat-out no. "We should be doing it ourselves"... BUT WE'RE NOT! Hence the need for a house keeper.

All I'd want someone to do is clean the bathroom, vacuum all the carpet and mop the kitchen (plus wiping the cupboard doors) and bathroom. Not a big deal. Maybe if I got someone do that, I'd get other stuff done.
I have 2 options, both I've known for years, so I'd have no problem leaving a key somewhere.

Thanks for all your replies... Now to just think about it a bit more and formulate my argument to DH.
