Investor/s for a movie - Executive producers

We are working with a screenwriter on the development of two English-language films aimed at international sales with well-known actors. We have interest from distributors after meeting with them at the European Film Market (EFM) in Berlin. We are looking for capital investors, we already have one found, as well as a shooting plan and budget. Once the financing is found, casting and realization of the films in Bulgaria can begin. We are looking for €2,000,000 for one of the projects (horror) and €2,500,000 for the other (action). The portion of the investment will determine the profits after sale.
