I just posted the modded starter save http://www.xpgamesaves.com/topic/80066-narco-terror-starter-save-with-max-money/
Tried it...money is 000000000. Think the money may be saved on the pro_0000000000 save file. I deleted the pro_ save from my hard drive and after loading my original saved games, sg01_, sg02_, and sg03_ with 3246 dollars, all went back to zero dollars. If you could mod it and upload both matching pro_, and a sg01_ saves that may work.
