When you say invest, do you mean long-term returns or short-term returns?
If you want short-term returns that will allow your money to rotate fast and grow fast, I suggest a business. Why don't you try retailing? It doesn't require a lot of capital, your P5,000-10,000 a month is definitely enough. There is fast turnover of inventory & you normally markup at least 100%.
So it's easy to get your money back plus profits. You then buy items again, and your money goes back to you double again. So it's a cycle.
If you want to pursue this, maybe you'd like to consider us. We just opened a new shopping center and we still have space for concessionaires at only P4,800 per month. We provide the display racks, the tinderas, and the management. So you basically just leave your stocks with us.
That's how I started too...
