I think it's a great attitude. But here are my two cents.
1. Buy the Panasonic GH2, and not the 5100
2. When I made my first movie, I had the same idea. "Hey, I'll write a story that I like. That'll mean that other people will also like it. If I truly like it, other people will have to like it. Then I'll make my movie. To hell with quality. That DP can go have sex with his lights. I don't need them. Sound? pfffft... I'll buy a good microphone and boom pole and a 30 ft cable. That'll solve everything. yeah.... people will come to watch my film in droves. They'll pay me a million bucks for the rights to distribute my awesome film, just like they do to those other people...."
It's not going to happen like that. I did make my first movie. I've shown it to live audiences (more than 50 each time) three times. Each time the audience seemed to like it. They even stood in line to ask me questions. But these audiences were mostly non filmmakers. They were just interested in story. They didn't care about anything else. But the filmmakers pointed out that my lighting was poor, and the sound was terrible. I still didn't think it mattered. I thought "What do they know? They're just filmmakers being technical."
But the reality is that if your movie does not look and feel and sound like there was significant amount of money spent on the production, distributors wont touch it.
From reading that one script, I think your dialogue is outstanding. I could see those people talking and I was definitely amused. I think it would make a good movie. But you just have to plan things a little differently.
I'm not saying don't make a film every two months. You can do whatever you want. I'm saying make a short every two months for the first six months with one day shoot for each short, so that you limit your costs and see how they turn out. Make improvements on the next one. Then make as many movies as you want. That way, you'll spend less money learning. Feeding people for 10 to 15 days or more days for a feature shoot can be very expensive, without you even realizing it. It was for me. And I only shot for 10 days.
You're 50 years old. You cannot afford to do it wrong. So do it right. Learn cheap with shorts. Figure out the problems and then go for it.
Best of luck,
