Freelance: so far, so good

I have talked to the Senior Technical Editor at the client I mentioned a few days ago, then looked at the various documents she sent me, and emailed to say that I'm interested and this looks like work I can do. The next step is that they have sent me, as a test, a previously published book chapter to proofread. I will be paid for this, though at a lower hourly rate than for live proofreading work. If I do well enough on this test, they will give me actual proofreading work, and possibly copyediting (which pays significantly better). My impression is that they are, if anything, in more need of copyeditors than of proofreaders.

The test is twelve pages and they want it back by the 18th of this month, which should be plenty of time (I have one other small proofreading job in hand right now).
