You need to contact experienced, qualified entertainment lawyers in your area to discuss this. Posting an open call on the internet (even a good site like this one) is not likely to get you where you need to be even if you get solicitations.
If you have a great idea you believe in you should find an attorney who believes in your script, treatment, pitch, ete and then retain them to shop the script, and perhaps create a worthwhile incentive for the lawyer or agent if the pitch is picked up for production. This might be your best bet to getting your idea promoted by an entertainment lawyer or literary agent.
This answer does not constitute a legal consultation, or definitive answer, nor does it establish a lawyer client relationship. Each case, controversy, or situation is factually different and requires particularized evaluation.
Avvo has a "find a lawyer" link at the bottom of the page. You would search for "entertainment lawyer" in your area, and this is what you would get: http://www.avvo.com/search/lawyer_search?utf8=%E2%9C%93&q=entertainment&loc=atlanta%2C+ga&commit=Find+lawyers
You can narrow the search by neighborhood, avvo rating, client rating, etc. That should get you started. You will want to review the lawyers' profile pages and see if you find someone who you think would be a good fit. Then interview a handful of people to determine who you feel most comfortable with.
Best of luck to you with your venture!
