I have always seen investors and grantors(?) as pretty much the same when it comes to your approach. If you would have to write a proposal in order to get a grant (and you will), you need to have a proposal to send an investor as well. I don't think it is realistic to just walk up to someone and say: "Hey, I have this great idea, do you want to invest in it?" I don't see that as telling the investor/grant very much.
Now, I don't know how to go about finding an investor, however when I had to write a proposal, the book I used was
Shaking The Money Tree by Morrie Warshawski. What that book did was tell me how to write a good proposal.
Because if you are going to want someone to give you money, you have to tell them what you intend to do with said money--in detail. Some questions might be:
How much money do you need? What's the budget? (obviously) What are you going to spend it on?
Do you have a schedule?
When are you going to start? How long do you expect it to take to shoot this?
How long to edit? When will it be done?
How do you intend to promote this? How do you intend to advertise this?
Who is your target demographic? Why would they want to come see this film?
Why are you doing this film? Why is it important?
How is it going to benefit society at large? This is a question I had to answer with my documentary, don't think for one second that the answer should be obvious. It isn't, you will have to explain it like any other proposal.
....get the book. Read it. Try to do what it says so that you don't just walk up to someone and ask them for money. You'll need to do the work so that you have an answer for every question.
This isn't to discourage you, but it is to at least get you thinking in very practical terms. Business is business and even more so when you are looking for funding.
