Bury Chairman Brian Fenton says without new investors the club could go out of business.
The Gigg Lane club need a £1 million injection after hitting financial trouble.
In a statement the club said:
"As you are well aware, Bury FC has been experiencing financial difficulties all season and we are currently in a transfer embargo imposed by the Football League because of our short term loan from the Professional Footballers Association.
At this moment in time the situation is now critical, we are quickly running out of money by trying short term fixes that are not working long term.
The club desperately needs £1million of external investment to secure the long-term future of the club.
Without this investment the club will cease to trade and there will be no more professional football played at Gigg Lane.
We are looking for a number of people, local businessmen or women to join a consortium and invest £100,000 each, with a guaranteed payback.
If you are interested please call the club and we will explain in detail our business plan.
We need you now because I repeat the club will close.
We have a responsibility to all of our staff, players and creditors to not allow the situation to get any worse.
This plea is serious; if you can help us and at the same time enjoy a return on your investment please contact the club."
