Brown is leading a consortium, named Rangers for Change, to try and take the reins from Charles Green's Sevco Scotland who took over the Glasgow club from Craig Whyte in June before entering liquidation.
Now, former 'Gers coach and head scout Brown is hoping he can help supporters gain control of the newco with ex-captain Ferguson, currently with Blackpool, keen to assist.
"I have spoken to Barry and he has promised me that he is 100 per cent behind me," said Brown.
"He is out of the country just now on a pre-season training trip, but there is no doubting his commitment and his enthusiasm for my deal.
"Because of his pre-season training and playing commitments it will be a couple of weeks or so before we will be able to sit down together and hammer out the details.
"But I can assure everyone how excited Barry is to be given this opportunity to do something for the club he loves."
He added: "I have meetings with bankers and lawyers arranged for the next two days and believe that by the end of the week I will be able to release further details of how Rangers For Change will work."
