The company you'll be most familiar with is CIT, they offer entertainment financing.

If you're looking for some industry sources then try Indian Paintbrush or Black Bear Pictures as a general go to. It would be helpful to disclose the genre of film, and how many minutes/scenes are set to be filmed (prior to final cut). I have a few contacts in the industry, if you can obtain a script, executive summary of the producers, etc. then I may be able to pass this request along.

Keep in mind though that the loan will be secured against the rights of the film and in some cases (smaller productions with novice filmmakers or obscure cast) the private equity firm may provide one of their producers and request market studies that could change the final cut and will also be a factor in assisting the bank in determining the valuation.

Shoot me a PM.

Dailyfunder isn't really the place for this.
