Not sure about the price, feels a bit excessive

Job description

Hi. I was looking for quotes for a media wall like this. I've had multiple quotes, the cheapes one being £2800. All materials included, including light fitting and paiting + paneling Obviously the TV is on me. I was expecting to pay around £2k, because my media wall would be only 2.4m. Can anyone that had something simialar to give me some fedback on this. Thank you Carl.
