The Scottish tactician has guided the Canaries into the top flight with back-to-back promotions and understands that he will need bring in some signings during the off-season.
But Lambert says he will not pay absurd fees for players as seems to be the norm these days.
"It is tough to get lads. Where does the money stop - or where do you actually start? I think the prices are really inflated. The money at the minute for transfer fees is out of control at times," Lambert told talkSPORT.
"We can only do what we can do which I am totally at ease with.
"We will try to get lads to the football club that I think will go and compete with everybody else."
Lambert added: "We are close on a couple at the minute and we will try and get them in by the time we get the group back.
"By the time they come back altogether then they can get to know each other and hopefully integrate with the ones that are already there.
"We need half a dozen or so to come in and give us a hand."
