Holloway is trying to strengthen his squad ahead of the new Premier League season after guiding Palace to promotion from the Championship, but has found it difficult to bring in new players.
He has missed out on deals he thought were close and has become exasperated by the length of time it is taking to secure signings.
But Holloway knows Palace need to act quickly after seeing his side slip to a 3-0 friendly defeat at Crawley Town in pre-season on Saturday.
He told Sky Sports News: "Myself and the chairman are going to sit down and have a look at the targets we have shot at, and go from a scattergun approach to the rifle. We have got to knock some targets over.
"Now we have found out what it might cost us, where we are going, I'm sure if he was here today he wouldn't have been too happy with that either.
"We have got to try and give the lads we have got a chance to feel good about themselves when in a couple of weeks' time they are going to start in the toughest division in the world."
Holloway added: "We have got to hone down some targets, but this week has probably been one of the worst of my life because things have broken down for all different reasons.
"It's just an accumulation of coming into this so late. I was half expecting it but it is a little bit worse than it's been before.
"I thought we were signing someone the other day and they went somewhere else. It's all a bit crazy really. You get phone calls, and phone calls on phone calls from people who are not even anything to do with the deal and then suddenly they think they are."
