Reputable, experienced agent wanted to sell screenwriter's scripts to producers, directors or film companies. Four are done, ready for pre-production or option, all of feature length and are registered with the Writers Guild. This is not a job for the beginner. It requires someone who has the insider connections with Hollywood and a proven record of successful sales within that industry. Screenwriter has agreement with an author to do his other five books as scripts and books are already published and solely owned by said author.
Of those done, two are of historical and factual content and never been done on film in their entireity. Another is a western done as a sequel to a successful movie in the 70's which starred the late John Wayne (no copyright violation) and the last one is based upon myth about a haunted lighthouse in Oregon. Two of the four can be filmed almost entirely in Arizona. Budgets would vary from low to high.
Compensation is just what the industry standard is. A flat 10% of what a script sells for after it is sold. There are no up front fees paid, again per industry standard.
For futher information make contact with an outline of your background and proven success.
I don't even know where to begin with this, except to say that even putting aside the foolishness of seeking an agent on Craigslist, this is a classic example of how NOT to write a query.
Let's treat this like those Highlights games and see if you can spot all the things this posting does wrong.
