The off-contract marksman, who shared the A-League Golden Boot with Besart Berisha and took out this season's Young Player of the Year award, could resolve his future by the end of this week with his Suncorp Stadium exit confirmed.
The 23-year-old's agent, Paddy Dominguez, has presented Maclaren with a smorgasbord of options, a reward for a 19-goal campaign for the club which came within a game of this weekend's grand final.
"There was a report a few weeks ago when I said there were over 80 expressions of interest in Jamie, well that was absolutely true," Dominguez said.
"And I can tell you now that there are even more ... they are coming from most of the big places in Europe.
"So he has to sit down now and make a decision as to what so the place he wants to go to.
"He wanted to postpone contract talks until the conclusion of Brisbane's season but with them having lost to Melbourne Victory on Sunday, we will move very quickly to secure his future.
"That could possibly be as early as this weekend. I would be stunned if he hasn't signed for a club by Friday week at the latest."
Dominguez, who masterminded Aaron Mooy's move to Manchester City and subsequent loan to Huddersfield Town, is plotting a similar course for Maclaren.
"Like Aaron, he has to go somewhere where he is likely to play," Dominguez said.
"Very similar to Aaron, if he gets one good season under his belt it will act as a strong foundation to springboard Jamie into bigger teams.
"Similar to Aaron (at Huddersfield), it might not be the sexiest big-name club but it will definitely be a very strategic move.
"I am confident that his first season will deliver a lot of goals and give him that landing in Europe that will draw attention from some big clubs."
While Dominguez didn't discount Maclaren moving to a marquee club like Manchester City and then being loaned out, as with Mooy, he said it was more likely he would simply sign for one team and play for them.
"What was right for Aaron is not necessarily right for Jamie," he said.
"In Jamie's case he will probably sign for that club and play for that club."
While Mooy has flourished in the Championship, Dominguez said Maclaren, whose father is Scottish, isn't wedded to the notion of signing for a UK club.
"The last thing you want to do is to take Jamie and put him in a league where they like to lump balls up in the air and pit a six foot six defender against a striker," he said.
"Jamie's game is very much about being a goal poacher, and playing with teams that play the ball on the deck.
"We will look at leagues and teams that play that style of football, to give him the best opportunity to do what he does, which is to score goals."
With the possibility of a June Socceroos recall for the 2018 FIFA World Cup qualifier against Saudi Arabia, friendly with Brazil and the Confederations Cup, Maclaren potentially has a lot on his plate.
"I don't know what Ange Postecoglou will do but if he does decide to bring Jamie into the national team fold, then he would have commitments in June which don't allow him to just sit down and mull over offers then," Dominguez said.
"Its going to be a matter of using the time in May to get ready for his next step."
