To give you the background, I got this job through an appeal on a local forum. I saw it but put it aside for a couple of months before getting in touch with him to see if he was still looking for someone to do the job. It seems someone did start it but bunged it back after a couple of weeks, saying she was too busy to do it. By the time I responded, he was pretty desperate to find someone, so I'm certain he's not going to want to let me go.
I told him I could give him a price for typing up and editing but not, at that stage, for the rest of the work. So we agreed on a price for the first part of the job. (He was also well aware that I'd sold myself short; I wanted the job and thought I could claw some of it back later). While he said he didn't want me dropping out, he really was fantastically unaware of the amount of work he was asking to be done, but when I sent him a written agreement, breaking the work into two stages, I think he understood it wasn't going to be quick and easy and, I strongly suspect, he was a bit shaken. The written agreement also showed him I was serious.
So the agreement states a fee for typing up and editing based on 80,000 words - his approximation - and that for all subsequent additions he will be charged £9 per hour. That's stage 1.
Stage 2 is proofreading and project managing the self-publishing side. I should have included the words copy-editing, here, because the whole thing will need re-formatting by the time stage 1 is complete. I stated that I will be able to give him a price for proofreading when I know the final wordcount, and I will also give him a price for project management.
While I've given him a price for additional pages, it's the extras I'm not sure about - as I said, time spent talking about and labelling the photos, thinking up chapter headings (and probably the book's title), translating into dialect where necessary (cross-referencing needed here, though I am familiar with much of it) and, perhaps, writing a press release for the local papers. There's also quite a bit of fact checking but that's included the job price.
I have established a relationship with the client, and when we last met, he told me we won't fall out over money. I just hope we trust each other as much as we appear to. It's interesting that I now know so much about him (because I'm working on his life story) and I see how thoroughly shrewd he's been in business, but he's also a very nice bloke.
