Over the last year or so I have developed a good, working and professional relationship with a fairly established producer. I recently sent them a script that they liked a lot but it does not fit their slate. They did recommend another producer who's work I very much admire. My question is, is it good or bad etiquette to politely ask if they're able or willing to make an introduction so that I can send the second producer the script? I do not have representation, so the most direct paths available to me are my relationships and network of contacts.
