Machala is keen to bring in much-needed funds due, in part, to a drop in attendances this season, yet he insists he is not interested in selling the League Two club.
Senior figures such as the club's chief operations officer, marketing manager and company secretary have all left Aldershot in recent weeks, while manager Dean Holdsworth's assistant Matt Bishop was the latest out of the exit door on Monday as part of what the club called 'restructuring on and off the pitch'.
Machala told BBC Surrey: "We have had some offers that are not suitable for the club. I refused them.
"We are still looking around and it might come from unexpected sources. We are in talks at the moment so we will see what the future will bring.
"I am trying to attract other people to put money in and we need some help from supporters and individuals to secure the club's future. We are not looking for new ownership.
"The club belongs to the fans, in my opinion, although I have the majority of the shares."
However, despite having to cut their cloth accordingly, Machala insists administration is not looming.
"I don't think there is any immediate danger of the club going into administration but it would be if we don't make the cuts," he said.
"We have stabilised the financial situation and the cashflow is mainly positive."
