You should probably start with one film at a time and raise the financing using a site like indiegogo, keep your budget small, and your story highly original. You need to study the global marketplace for film acquisitions to see who is buying films and who the top sales agents are for a film like yours based on genre. Also, submitting a film to as many film festivals as you can afford is also a must, including the 50-100 film festivals that do not have an entree fee.
