I am aware of. I'm sure that because the Hollywood Studios do product endorsements so often they have a good idea of what they can ask.
However, you're in a wide open game if you're doing an indie film. This is a difficult area to obtain hard cash from but easy to barter. Getting car rentals, catering, costumes, locations is your surest bet. Talking large corporations (Coca-Cola) out of endorsement dollars is very slim. You won't even appear on their radar in most cases unless you have an inside connection.
Good luck with your film.
