How can i make my own Horror film with no experience one digital camera, compute!

How can i make my own Horror film with no experience one digital camera, computer, my crew and a low budget ?

I want to do this for a fun Halloween activity "my crew" will be my family. I just want to make it to put on youtube.com but if you have any better sites to post a homemade movie please list it. I am hoping to spend under $200 for the stuff. Do I need a permit for making it-I read a previous question just like this and the answerer said that you need a permit remember I will just be taping in my family members home. I am going to do this on Halloween night so no body wonders what is going on.... are there any ideas that you want to give me such as masks, props, clothing, special effects, ect.? I want to make this movie between 1 and 1/2 hrs and 3 1/3 hrs. Any ideas that will make it extra spooky? I want it to be like a slasher movie similar to halloween. Please list any sites that have the items that I should buy. or any sites that tell ways of making things look as realistic as possible. Once again anything at all will help.

Thanks for all the help,
Funny Monkey.

Wish me luck?

You don't need a permit if you're shooting it at home, only if you're shooting in town and will be disrupting business and/or traffic there. YouTube limits video uploads to only ten minutes, except in rare special cases, so try to keep your movie under that length. Start with the script, keep the concept simple, and go from there. Below is a great YouTube channel with lots of great tips on low budget filmmaking.
