Do you think this internet cafe would be a good investment? Please give comments and suggestions. Thanks.?

My father and I decided to start a internet cafe. So, we will buy a more or less 150 square meter house and lot and we will start with 15 unit PCs. We will also add a billiard table and also a coffee shop that serves finger foods, sandwiches, juice and maybe some beer(or no beer)..... inside the 150 square meter house and lot. The house and lot is located inside a subdivision in which there are no internet cafes nearby. The nearest internet cafe from the sbdivision is far and has few and old PC units. We will buy all LCDs and maybe 3 Dual Core PCs, Intel Pentium 4 processor PCs, AMD processor PCs with video cards that reach 128mb and up. It will offer typing jobs, photo editing, scanning, Video Editing, etc... So, is this a good plan? Do you think it will be successful? If successful, we plan to again invest in another business here in the Philippines. My dad said that it is an advantage compared to reniting in the mall because all profits are ours and we don't pay for rent.
