I did find some helpful information by a lady at
www.creativescrapbooking.com. She gives lots of typical ways people charge for this service. Some by the page; some by the hour; some by the book but overall she stresses to not undercharge -- you can always discount without a fuss but try to increase your fees and you'll get a fuss. I think I'm going to go with an hourly rate. Some books will take longer depending on what the customer wants and I just don't want to charge a per page fee when I may have to end up spending more time on some pages than others. I know the pitfall of this is having to keep very good time records but I think it's easier in the long run and I'll include the documented time sheet for my customer. I can give an ESTIMATE of how much time it may take but will stress that this is not a definite fee and can go up or down depending on time spent. We'll see . . .
