Who can provide professional assistance and support in organizing mutually beneficial relationships with investors.
Nobody can/will do it for a random person over the internet.
I suggest you make a proper introduction of yourself and your idea. And to start the relationship correctly, do not sugar coat your idea. Be honest.
You are right and when investors do see that honestly and seriousness about project proposals then it would be possibly able to caught their attention which might result into some funding support.
Don't sugarcoat or having that deceiving kind of way on suggesting or presenting things because sooner or later they would really be able to know on whats the truth.
Show passion, honesty and of course your dedication towards the project.Investors aren't really that dumb on not to see those behaviors and qualities.
