You can search for film people by region here: https://www.stage32.com I've found some crew in my area to work on a short film, it was very helpful.

If you have an event, like a theatrical screening even just at a small art house theater, that might get you some local press. If you get into any film festivals, research the press in that area and send them your press kit and a DVD that they can watch at their convenience.

You probably want to start with interviews and as the others have suggested shoot them inside, behind closed doors. You can also get lots of b-roll inside with the people you interview. Even shooting mundane, every day things can be beautiful and even meaningful. And if your movie explains how difficult it is to shoot any footage in your country, the audience will understand why so much of your film is trapped inside. You might think of shooting a documentary only from inside locations as a challenge. How can you get creative with your shots? How many different ways can you shoot one room? Try putting your camera on the ground, on the ceiling shooting down, try some time lapse footage.

Then if you want to be really bold and don't mind the risk, you might think about hidden cameras for outside footage. Gopros are small and fairly easy to hide in a bag or under loose garments. Be careful, be safe and don't lose hope.
