If you were going to use the ol' "sell 'em my maps" scam, go ahead and use the "add_money" cheat. It would solve your problem.
I sense that your greater dissatisfaction is with your starting financial position then anything else. Everybody plays this game to have fun. Go ahead and use the cheat, you will find that as you play the game more, it will draw you in with it's complexities. The EB mod is as realistic as can be done - although the EB team is always striving for the next level.
By your second or third campaign, you will chuckle at the thought of the "add_money" cheat. But for now, use it and have fun - but remember the golden mean - nothing in excess, my friend.
