How much to replace internal doors and frames?

[Paramaribo0]

I have 5 internal doors which I would like replacing and also the frames as they have 30 yrs of gloss and they don't fit the doors very well. Would a carpenter be able to do this? And would it be hideously expensive? If anyone has any experience of doing this I would be grateful. Thanks.

I had 5 doors replaced earlier this year by a carpenter . Nice panelled ones.Cost of fitting and furniture but not painted( did that myself) was £ 500. Was loads more work than I thought.
