Producer: We really want you on this project, but we don't have the budget to pay you...
Me: Oh. Okay. Well, let's see if we can work something out. First off, what are the dates?
Producer: Next month from the __ thru the __.
Me: Oh... Sorry. No can do. I'm already booked on another job those days.
Producer: But we really want you on this project.
Me: Yeah, I understand that and I'm really flattered, but I have bills to pay, you know? The only way I can work with you guys on those dates is if you paid me.
Producer: What's the lowest you can go for us?
Me: (I give them a rate that's actually waaay lower than what I'm getting on the other shoot.)
Producer: .... I don't think we can afford to pay you that.
Me: I'm sorry then. But thanks for thinking of me and feel free to give me a call for the next one.
Producer: But... we really want you on this one.
Um... Then pay me??
