I'm sorry if this is not a Blog as such but I need input from as many people as possible. (Is there another section where I should be posting?)

 I have been asked by a senior to record  her life story, type it up, print and compile into a booklet. I expect she willl also want pictures included which would require my copying (I'm thinking of the price of ink!!!). She wants to pay by the page. I have no idea what to charge her or whether to present her with the individual segments of the process and individual costs to her. Even then, what to charge??!!  I've looked on Google but those prices are for professional writers who need to make a living. I don't need a living cost charge as I am retired myself, but neither do I want to put time into a project and incur costs without receiving any fair recompense. I know seniors (she is in her eighties) are often shocked by prices and I don't want to appear to be greedy or trying to take advantage of her. Help!!!!
