You have not still answered which country are you from and where your movie will be broadcasted. As you mentioned you spent over 1000 hours to make this documentary, well it hardly looks as though you did it just for fun or to practice "adobe after effects". You are asking for free help while keeping your reasons hidden for a possible helper. Since your documentary covers the military conflict it is obvious that people want to know whether your movie will be used to support only one side to win the conflict (which can cause a lot of casualties) or to stop this conflict from both sides. Providing any help for a stranger for free people have the right to be sure that their help will not be used to cause any harm to other humans.
