How much should I expect to pay for a DJ and a videographer

Not sure on a videographer. Our DJ was included with the venue but when I saw the breakdown on price it was £350 x

My dj is 500 but that's with venue if I chose a different dj I would have to pay venue 400 . My videographer is 750

When looking I think Videographers were about £1000, and our DJ was already in the hotel package x
