Looking for carpenter/handyman to replace section of fibreboard under carpet

Our plumber managed to make a small hole in the floor when pulling up the fibreboard under our bedroom carpet to find a leak. The leak was fixed but the floor hole is now a larger hole and we think we need to replace that section of fibreboard entirely. Hopefully it's a v easy job of just getting the carpet up, then cutting a piece of board to size and hammering it in, but we think it's probably beyond our DIY skills! Any recommendations of someone who might be able to do it most appreciated! Thanks in advance
