Pitches don't sell like used cars or like emphemera on e-bay.
Let me qualify this by saying there are exceptions to everything - as there are to my following response.
But generally speaking, you cannot sell a pitch.
Hollywood doesn't have an open door policy where people just come in and pitch ideas.
Selling pitches is mostly reserved for
established writers and producers. Anyway, ideas are a dime a dozen in this town. Everyone has a pitch. Hollywood is more interested in completed screenplays - the full execution of the pitch. And even scripts are difficult (almost impossible) to sell.
It is unlikely that any reputable production company or studio is going to invite you in to pitch. Unsavory producers (with no track record) might be willing to hear your idea but will not pay you or will rip you off in the end.
The guy with the idea isn't worth all that much. It's the guy who can execute the idea that gets paid all the money. ("Execute" is defined as writing the screenplay or producing the film.)
If you have the desire to write a script, I would suggest developing the pitch into a screenplay. If you want to produce it (which would entail finding a writer, paying him and rounding up money & a cast and crew to make the film - a very expensive proposition) then give that a whirl.
There are "pitchmarts," where you can pitch your idea to film executives, but if they like the pitch, they will want to read the script. And the real success rate of these pitchmarts is less than a half percent.
It is unlikely that anyone will buy a pitch from a detatched entity - unless he has strong roots in the Hollywood community.
This business isn't for dilettantes or dreamers who don't want to do the work.
P.S.
I encountered a zillion e-mails not too long ago with similar questions. Here is part of that story:
