Most services tell you how to fix your script so production companies will option/buy it, and naturally they claim they know exactly what production folks want in the first place.?Really? First of all, different companies want different things. Some have no idea what they really want until they see it. Most don't accept unsolicited scripts at all. A reputable agent might help but try getting one.
What you need is an honest chance:
-a few brief notes on your story and characters
-a strategy to move your story out of your house and into the playground where films are made
