I feel a little bad for just dismissing this outright without providing some bits of constructive feedback before, so I will try to give you a little advice.
You need to approach potential investors with more than a loosely formed idea. This means that if you intend to build this yourself, you should bring a prototype of the application. If you haven't developed a prototype of the application yet, this hurts your efforts a lot, but if you really want to persist without it then you need to at least have the specification written. It needs to be in clear, precise language.
You should proofread all of your communications, as they leave an impression on the reader. While being well-spoken does not guarantee you funding, demonstrating poor communication skill will definitely create obstacles. If English (or whatever language you're addressing your target audience in) is a second language for you, you should have a native speaker review it for you before posting. You need to trust that this person will actually review and fix or point out any grammatical/syntactical errors for you instead of simply saying 'Good job!' or limiting his or her feedback out of a sense of compassion for your feelings.
thank you really for your advice.
