You can start your own printing business. Start small first, calling cards, posters, shirts, etc.. Your supply of inks, silkscreens, printers, and other raw materials are essential to this business.
You can start your own meat processing business. Go for the sausages since that's what really selling right now. Try to attend a workshop in TESDA, they'll teach you everything you need to know and even how to make your own equipments.
You can open a mini grocery/convenience store. It's all about location. Find a strategic location and fill in that spot.
If you love the liquor and the nightlife, you can start your own mini bar. The ROI of liquor is about 60-200%, depending on your pricing and of course, your environment.
Or if you'd like to go for franchise, there are a couple of available franchises such as: House of Panini, Jell-o, or Mom's Pizza.
But, I'd suggest that you first have to identify where your interests are. Automotive, computers, business, marketing, advertising, events? It's easier to find a business if you are really passionate about something. Share your passion to everyone. Nothing beats that!
