If it was ME, I'd be thrilled that you found someone to clean the house...but that's just me, and I don't like to clean.
BUT, if I'd just talked to you, and told you I WANTED to help, then I wouldn't expect you to hire someone to do what I WANT to do.
You could say, "Hey, since I know you're so busy, I found this company that will come clean houses for only $xxx. So, I was thinking I'll do some grunge work, like clean the bathrooms for that star picture you're looking for, and repair the holes in the walls, and then have this company come and polish it all up. What do you think?"
That way, you're not perceived as being lazy, she can still help if she wants, and likely you'll get most of your security deposit back.
That's my opinion.
