Internal door fitting

[GatheringRequirements]

Hello MN'ers
We are looking to fit two internal doors and has been quoted £120-180 for normal doors with glass panels, nothing fancy, is this reasonable?

[CountingToThree]

we've been quoted between £40-£60 a door in the past (the lower figure when getting 6 fitted at same time) and doors already had handles and hinges fitted so it seems to be in the right ballpark.
