The Canaries have been strongly linked with Celtic's Gary Hooper, with one bid having been knocked back by the SPL champions.
An improved offer is believed to be in the pipeline, but Hughton concedes that Norwich are in no position to match the kind of money being flashed around by Queens Park Rangers.
Harry Redknapp recently drafted Loic Remy into his ranks for £8million, but there is little chance of the board at Carrow Road digging so deep.
Hughton said: "We want to bring in more attacking options, but people don't understand how difficult it is.
"I see QPR spending big money and bringing in Loic Remy and that's where they are and what they are able to do.
"There are a group of clubs able to do that. We have to do things our way.
"We need a player who is going to benefit what we are about and we will keep going right the way through but it's never easy."
