I'm just wondering.... do you want to sell the house at all, are you just stalling and coming up with reasons why things can't be done a certain way?
If you don't want to sell the house and you want to keep it, that's cool, have you told your wife that?
If you do want to sell the house and don't want to pay for house cleaners just be up front about it with the wife, just tell her
"look I want to sell the house as much as you do, I really do but with the amount of work I've put in the house thus far it just not fair to me to pay half for the house cleaners, you pay for the cleaners out of your pocket and you can have them in here tomorrow, I have no problem with that, I've just spent too much of my own money and invest too much of my own effort, time for you to put in some effort & cash if you want to move this house, plain & simple otherwise we can sell the house when you're ready to get involved in this effort."
