So they want $2400 to weld in two extra floor joists to an undamaged floor? That is outrageous.
I wonder if you could bolt-in two supports yourself. Buy material like THIS
. Bolt two lengths together back to back, to make a strong "T" beam. The material is easy to work for cutting and bending mounting flanges. It is also galvanized for corrosion protection.
If you make such a "T" beam and find it "flexing" more than you want, add a 3RD FLAT PIECE
in between them.
