Part of that has been used to finance the GB team's trip to the United States.
"The funding has been a real boost to everyone, because more competitions means more experience," said Cook.
"The US Open is really important to me this year because winning would give me the points I need to secure a good ranking at the World Championships, which are my main focus for 2011."
Cook capitalises on controversial win
Great Britain have four guaranteed host-nation births for taekwondo at the London Olympics, two for male and two for female fighters.
Results at the World Championships in Gyeongju, Korea, from 1-6 May, could be key to deciding who makes the cut for the 2012 Games.
"We have to notify the
World Taekwondo Federation
which weight categories we're nominating (for the Olympics) by the end of May this year," said GB Taekwondo performance director Gary Hall.
"We can only name four fighters in the squad so there will be some tough decisions ahead, but it would be very difficult to ignore anyone who wins a World Championship medal.
Success in Korea, the home of taekwondo, would complete a remarkable few years for Cook who at 17 was
controversially denied a medal in the play-off
for -80kg bronze at the 2008 Beijing Olympics, when he faced home-favourite China's Zhu Guo.
The Brit made his mark on the global stage the following year, defeating world and Olympic champion Steve Lopez in a World Tour event in Mexico.
Further success followed in 2010 when he became British and European Champion.
"I've had a great run of results, but now I really want to add a world title to my collection," he said.
"London (2012) is of course on my mind, but I have to just focus on the next fight and try to win. That's what will get me the points and the titles over the next 18 months."
Cook confesses that without the support of his parents none of his achievements would have been possible.
Meet GB Taekwondo star Aaron Cook
He left home aged just 15 to join the GB Taekwondo team, which was then based in Loughborough. Following the team's move to Manchester in 2007, Cook was joined by the rest of his family who have continued to back his career.
"They've been amazing, driving me up and down the country to competitions since I was five and even travelling out to events with me abroad," said Cook.
"There has been a lot of sacrifice, at times they've been working two or three jobs just to help fund me, but it's all helped to get me this far and hopefully it'll get me on top of the podium in London."
And Cook sees staying at the top of his sport and claiming further honours as the perfect way to say thank you.
In the here and now, the US Open is the focus for Cook but the Great Britain squad is missing two strong medal prospects.
Bianca Walkden, the 2010 World Combat Games champion from Liverpool, has been ruled out with a knee injury, whilst Beijing bronze medal winner
the women's -67kg world number two, has withdrawn for personal reasons.
The team does however include 2010 Youth Olympic gold medallist
from Wales, who will be making her World Championship debut as a senior.
