What's a fair price for venue posters?

1 year ago from , Designer

I was offered some freelance work to design posters for a venue in SF. I've done posters before, but now primrily focus on UI design, so I'm excited to flex my graphic muscles again.

It's a big venue (space wise) but up and coming as far as music shows go. What's a fair rate per poster? Obviously some may be more than others depending on involvement, but how can I get a good idea for a range?
