off pi#ps topic. i can use some help.

hello everyone. i hope i can post this here. i am wondering how i can go about finding investors in an idea that i have. i came up with a motorcycle engine design that will compete with the asian and european sport bike markets. i currently sent the idea to invent-tech and they are going to show the idea at a trade show in september. i was wondering if/how i can start an investment program to fund the production of this engine design and eventually fund the production of a complete prototype motorcycle using this engine design. my current background is motorcycle/automobile mechanics. i would really like to find a partner to help me in the bussiness aspects of this as it is not my experty. any help or comments would be greatly appreciated.
thanks for your time.
