Thanks for all the feedback here. For the record, I don't think the professional I was trying to work with is a shyster by any means, and I think I might have projected the idea that there was some animosity during our negotiations. I was able to check his credentials, and he's solid. He's also worked with some other crew members who are already attached to my project, who I've worked with successfully many times on other gigs. The filmmaking circle in Austin is pretty tight, and word gets out. Bottom line, he responded to my low-budget indie crew call, but I think this guy is used to working on much higher-end productions for much higher pay, and he was ready to bring the big guns to my little knife fight. The recorder he owns is Zaxcom Nomad 10 HDD recorder, for the folks who asked in earlier posts. He owns it, and was willing to rent it to me from his own stash, which was the only thing I found a little off-putting… if he has the gear, why not bring it and just use it. I think it was a matter of him already working for a much lower pay scale than he was used to, and adding his own gear onto it would have been pushing it too far. Anyway, in the end, we discussed my workflow and endgame expectations for the project, and he agreed to come on board. Sound will be recorded straight into the camera (by way of a mixer, as he monitors). Maybe he’ll come around on bringing his recorder and using it for dual recording, but it’s not a huge concern for me. I’ve been plugging audio into my C100 for years now, and it’s always been solid. I can only assume that having a sound professional to boom, mix, monitor, and prep the environment for proper sound will only improve an already good thing.
