I don't want anyone sending me scripts in hopes that I think they are great, and will pass them on to someone else. I'm not going to do that. If they are great, enter them in a contest. Win. Become rich.
I want to read scripts in which the writer is stuck, or needs a push, or some direction. Where I can give you pages and pages of story/structure/character notes, and you'll happily launch into a rewrite.
I will tear your baby apart. I'll tell you a few good things, and then most of the report will focus on what doesn't work. If you don't want your baby torn apart, don't hire me.
What I'm offering is basic, solid notes (no synopsis, just notes), from a guy who has read a hell of a lot of scripts and books (I'm going to hit my 9000th studio/prodco coverage sometime next year) and who'd be just as happy reading your script as he would one from a production company, for the same price. Because that's fair.
