Is there a salesman who specializes in sponsoring and looking for investment in TV dramas and movies? I just want to find someone who specializes in finding investors to make movies and TV series.

First of all, come up with the planning scheme of the film or TV series, the expectation of investment and recovery, the analysis of the income market, etc. , basically called outreach production. Generally, you contact the film and television company and start looking for small companies to learn from. After you have some experience and contacts, big companies will sign contracts with you.
