I'm asking this because I'm very determined to start a business, but don't have a clear idea on what to do, and by using this approach I could possibly get some investment if I execute in a high-quality manner.
It depends. If you're thinking you're going to walk-in cold to a VC's office, ask them for money and tell them you don't have a business model and want them to suggest something, they're going to get very annoyed and show you the door right away. VCs evaluate hundreds of proposals a day and they don't have time to waste on ideas that haven't even gotten off the ground.
However, if you develop a personal relationship with a good VC, you'll find that they are very happy to advise you in this area. The key is to be very respectful of their time and expertise.
Good luck.
