How to buy a new territory - a couple of questions

[clawfinger]

Sneaksie, could You answer these questions, please, as a person in close contact with developers?... It's really important, at least for me... ;P
Correct me if I'm wrong, but to open a new branch you need to have a lot of money, high rank and your company should also generate high income/revenues (is that all?). But what are the exact numbers (of rank and revenues) the game is interested in to open first and the cheapest branch?... For many players this seems to be the bigest secret of the game... ;P

And last question for experienced players: what (actions) would You recommend to quickly increase your income/revenues?

P.S.:
Forgive me my English...
