"But, as with anything, you are paying someone who knows what they are
doing
to fix what you can't. I would think that you could find a handyman to
do
it for about $25."

Unlikely you'll find anyone to do it for anywhere near that price or be
satisfied with the result. This job is going to take several trips,
because you have to do it in steps. I wouldn't do this job in a house
next door for that price. I'd say figure on $100.
