Before you start something in Angeles City you might want to spend some times talking to ex-pats there about their experience. You might change your mind after a few conversations.
One important thing to consider is which economy you plan to connect into. If you want to make an USA kind of income then you are going to have to have tourists as your client base. For the most part ex-pats that live here are living on a Philippine budget. Your not going to get rich owning your own business here. However, you can cover your living expenses.
Here is an example: Rent is 2500, electric: 3500, water: 1000, food: 150 per day: 5000, internet/tv: 1300 = 13,300 php per month. Plus any extra you want to spend. The billiard table alone brings in about 10,000 per month. If you know how to run a Sari Sari store you can make your cash flow. Anyway, just an example.
You need to live here for 1 or 2 years and learn the culture before you think you are going to hire employees and make a profit. My biggest advice is to start very very small, and dont be in a hurry. It really is going to take you 1 or 2 years to learn enough to gain your confidence. That said, maybe my experience is different than others.
