Try shorts, Dan. Start with a simple story you can sum up in 1 sentence and just let it unfold in a couple of pages. Scrap any side plots and focus on your 1-sentence story, keep it clean.
You'll have a much easier time getting those done by anyone and you can make contacts that way which will bring new opportunities.
My first short was found here via STS by a producer from New Mexico. He turned it into a film and the film was accepted as the Las Cruces International Film Festival. I was invited there as the writer and was able to make invaluable contacts.
A second short was optioned like 2 months ago through Script Revolution, shooting starts at Oct. 5th. And we're currently in pre-production for the first feature, the guy who directed the first short is going to direct that one in a low budget range and I'm co-producing.
At some point you'll just have to get your scripts out into the world, I think I've given you that advice some years ago already. If you're too scared to show your work to anyone who could do something with it, it's not going to happen. Don't worry about black lists either, it's a fairy tale. You can't get anything worse than a pass and even that doesn't mean your work is crap, the next one who reads it could like it and pick it up - it's all a matter of taste, there's no 'right' or 'wrong' in a creative task, writing isn't math.
