Wales international striker Craig Davies stands as the only acquisition to date after Wanderers met a release clause in the player's contract at Barnsley.
Davies' career is yet to take him to the top flight and Freedman insists he will continue to follow a template of players displaying hunger and potential to improve when adding to his already well-stocked squad.
"Yes, we have (got more business to come), we've got one or two things," he said.
"Managers say it's very difficult for them to sign players because there's not a lot of good players out there, which is true, but I think it's doubly hard for myself and one or two other managers who have got to sign a certain type.
"The secret right now is out that I'm going to sign players that are maybe not better than the ones I've got but have got the potential and the desire to be better.
"That's hard, to go and sign potential. Trying to go and uncover and discover potential and then go and sign it. That's what I'm trying to do and I believe I'm very close with one or two players out there."
