, free washer drier, day care nearby.    

The washer and dryer were in great shape so we reused those.

I'm located in Chicago and I'm looking for a local recommendation -- I need to hire someone to move a stackable washer and gas dryer from a 2nd floor unit to a 1st floor unit.  

If I was going to fix this plan within the bounds of the existing walls, I would do this:1) move the kitchen to where the front bedroom is.2) Cut the back wing of the house into 3 bedrooms and 2 bathrooms and slot a stacker washer/dryer into one of the bathrooms.
