You could make a movie about barely literate people who are geeks and can't act! Seriously, one thing I learned in film school is only write what you know. That's why I made my student film on pizza delivery since I worked in the pizza industry for many many years. I was able to use the restaurant I worked in as well as the uniforms, the pizza delivery bags, and it was all for free since I worked there and my boss was cool. If you can come up with an idea where your friends can be themselves then it lessens the worry about poor acting since they won't have to really act all that much. Think of what you've got, where your parents work, where your friends work, the geography in your area etc. Come up with a story based on what you've got and what you know and it might all come together. Keep your friends in mind that hang out with you the most. Good help is hard to find when everyone you know has full time jobs. Otherwise, if you've got some money, many people will easily find the time to help you if they get paid, but I know I couldn't afford to do that at this point in time. Sounds like you've got the proper post production software and hardware which is a huge necessity you've already taken care of. Man, I wish you lived by me because it sounds like I've got what you need and you've got what I need. I don't even own a computer.
