Ghost of the load bearing wall - contractor recs?

The 3 story house we just bought had a load bearing wall removed from the second floor decades back. A post was put in place that now seems to be breaking through the subfloor in the floor above. The floor beneath the post shows signs that it may be being pushed down by the post . I would love to have the post replaced with a more appropriate solution perhaps a beam across the ceiling. All of the signs of this issue were covered up by very thick and padded wall to wall carpeting and slid by the inspection. So far, all of the recs I have received for contractors have been booked. Would love a referral and any advice.
