I believe you should focus on providing work and jobs for the newer generation of players here on Argonath. By that, both parts will earn money. Before you start your corporation, you should always focus on getting a stable and respectable executive board (ExCo).
To earn money, you need to do something, driving around in fancy cars doesn't give any profit, does it?
Easy way to start earing some money, is to have a product to sell. After some time, you can expand to different types of business. For example:
Many people start with a lot of subsidiaries at first, which makes the corporation unstable and will after some time fall bankrupt. My tip is that you shouldn't start with a lot of business at once, take some time and devlop something unique instead of going straight on the estate business, which most of the corporations does.
Having a small amount of assets in another city doesn't make any change. I suggest you to focus on once city, and when you manage to have a small amount of employees, you can set out different divisions in each city. But always focus on one city.
