I am looking for money to make films and watis the most suitable way

I have no idea, but I would tell you to get with other film making companies. They probably could give you some information on how to go about this. I too was trying to get my song into movies, films or documentaries. I contacted a few video companies and one of them told me about this online publishing company. So, I would suggest that you talk to or call someone who is already in that field. Much success to you.
