Twenty years ago, I probably could have done it all and then some, but the years and CFIDS have taken their toll on my ability to do things and/or to figure things out. So you're right: I am female. And I'm still trying to find someone who has a drill so I can elevate the Laz-E-Boy onto a couple of 2X4's so it isn't so hard to get out of. I also need someone to drill a hole in one of the legs of the laundry cart and insert a long screw so the basket isn't permanently skewed.
I was spoiled for a good many years when I was younger, because as a military wife, I learned the only person I could depend on was me, and I could fix almost anything. Not these days...
You would also need a drill set. And to fix the file cabinet, you'd need a couple of steel rods about twenty inches long. (Figure out where the rods should be to support the hanging files, drill a hole through the back side of the wooden file drawer, and only partly into the front, from the back side. Slide the rod through, fix it in place, and hang files on it.)
Or go to Walmart and buy a cheap file cabinet and rob its innards.
