House Settling Issue

[Krishna Vakk]

Hi all, I recently purchased a house that has settling issue. One of the contractor told me that he will put pressure treated wood to support 12 floor jacks across various places in 20X10 basement area and make a 3ft deep concrete base to place jack post to stop settling for $6200. Other one gave me a quote for $5000 to install a 20ft galvanized I-steel beam and support the beam with 5 jack post with concrete base. Firstly, which method is more preferred and the quotes that I received are reasonable or shall I look further? TIA Any inputs are greatly appreciated. Property is located in Carlisle PA.
