I had a similar problem a few years ago. I got two proposals. The first one
was to install 2 screw jacks over new concrete footings (about $1,000). Most
of the cost was the time to pour the footings since a lot of digging in a
very shallow crawlspace had to be done by hand. The second solution was to
replace the 2x8 feet span wood beams with one steel beam. I think the cost
was approx in the $5,000 range.

use two, use a 4x4 from the top of the jack to the bottom of the beam.
Strp the 4x4 to the beam so it doesn't fall. Jack it up in small
increments over a long time at you r leisure. When the beam is up
where you want it, remove& replace or repair the brick column & it
foundation, let the beam back onto the column.

Unless you're really handy & know exactly what you are doing but
discuss the fix with an engineer & you can DIY with confidence. It
you did this yourself your cost would b minimal beyond the engineering
consult., it's mostly time

btw yes a steel beam can span 24' but again you need some who
understands the construciton of your house & can do the calcs.

in defense of the contractors, time is money; they want to get in & get
out fast. Old houses typically need a lot of TLC. Not exactly,
compatible with contractor way of doing stuff, unless it's T&M.
