Another place to start is the local library, especially if they have the equipment (16mm or 35mm projector) or a screening room.  Places like Kino, New Yorker Video, and World Artists all have rental services.  Kino's published rates are from $100 to $1000 (for more popular/recent titles).  New Yorker Video actually has Kiarostami's "The Wind Will Carry Us" and Hodges' "Croupier" available for rental, but I'm sure the price is steep for those.
