I got an inquiry from an author who likes my work and is interested in having me design the front and back cover for his novel.  He also asked about price.

The problem is, I have no clue what to charge.  I've never done this particular type of commission before.  Since he mentioned both front and back cover, I'm assuming it's got to be a spread of back-spine-cover.

I would really appreciate some advice/info from anyone here who has done (or does) this type of work.  I need to get a rough idea of what kind of prices are reasonable, expected, the norm, etc.  You get the idea.  :)

And please, comments like "charge as much as you think you're worth" will not help me at all.

TIA!
