Note: Always make a backup copy before edit a game file.
Start the game, then begin any single mission and immediately save the game. 
Quit the game. Locate the "*.save" file that  corresponds to that game 
session in the "save_game" folder in the installed game directory.
Open the file with a text editor and search the following string:

[COLONY_GENERAL_DATA]

You will see some digits after that. 
The format of the numbers should resemble: 
722546.000000 43900.000000 

To change the amount of money in the mission, modify the second number 
to any value desired. 

For example, change "43900.000000" to "4390000.00000".

Purchase the Atlantian Monument by building a school. Build it then construct 
a warehouse. Then, build the Atlantian Treasury and fast forward the game.
