Steve Housham insists Gainsborough Trinity will not "chuck money around for the sake of it" as he prepares to intensify his recruitment drive.
The Blues boss believes he is two or three players short of the squad he wants for the new season which kicks off in little over a month.
Housham has already been busy in the transfer market having signed Greg Young from Alfreton as a replacement for Andrew Boyce, who has joined Lincoln City.
Highly-rated winger Terry Hawkridge and defender Josh Wilde have also signed from Carlton Town and Buxton respectively.
However, Housham has not finished in wheeling and dealing and will run the rule over a vast number of trialists.
But he said Gainsborough would not be throwing money around on just anybody.
"We are going to have a look at a few players during the summer and a lot of them will play in the first two friendlies," he said.
"It's up to them to impress us but we will not chuck money around for the sake of it.
"We will be looking at these players and making sure they fit the identity of the club.
"The players we want have to want to work hard and be successful, not just look to come here for a wage packet.
"I want them to show to me they want to take Gainsborough to the next level.
"We have had lots of CVs in from players and we've sifted through the ones that we want to run our eyes over. I don't want them to try and over impress, they have to be natural and I will soon know if they have what it takes."
