A couple of things when seeking capital investment. First, you never say how much you are seeking. Second, you never say what an investor is expected to get in return - are we just supposed to give you money and then walk away. You also never state your experience in this space. Do you have experience? Most investors do not invest in products or companies - they invest in people - people who can pull this concept off.
Think about it this way - you can have the greatest idea in the world - but, if you can't execute it - it will only remain an idea - no matter how much money you throw at it. I have seen great management teams take average ideas and make great businesses out of them - all because they know how to execute.
I suggest you find a local SCORE or SBDC in your area - both are free to use. They can help you research and develop your idea as well as point you to local capital resources.
If you choose to continue to follow this path (public solicitation for investment) - I suggest you read the SEC's rules on such (start with their Reg D).
