As long as you’ve registered your script with the WGA and gone through
the whole copyright thing (which you should do with any full length script,
even if you’re trying to make the film yourself), you’ve got nothing to worry
about. Just don’t sign away the rights to your film without proper payment
first.
Any sort of writer serious about selling his art knows that query letters are the
way to go. Granted, if someone shows interest in your work you might have to
do a little research to make sure that the said person is with a legit company
or maybe even hire a lawyer/agent to look over the contract before you sign it,
but unless you know somebody query letters are the easiest way to “break into
the business” if you don’t have the means to make the film yourself.
