Club Concorde, made up of former captains, charterers and aviation fans, says it has £120m in reserve to resuscitate the airline.
The group also plans to put another of the supersonic aircraft on permanent display in central London.
Concorde, which can travel at twice the speed of sound, last flew in 2003.
Negotiations are now under way to try to purchase or lease the two aircraft. Club Concorde president Paul James said they were hoping to source both the display and flight jets from France but no agreements had yet been made.
"We have been overwhelmed by the amount of enthusiasm and people wanting to invest," Mr James said.
"The support shows how much people still admire Concorde and want to see it flying again.
"The plane we would like to get in the air is at Le Bourget in Paris. We had wanted to lease and restore a British Airways Concorde for display in London - next to the London Eye - but this has not been possible, so again we are looking to France and a Concorde near Orly airport."
After restoration the plane would be used at airshows, for special events and private charter, Mr James said.
