I have to submit a bid to edit a how-to book, workbook and sales letter for the project. Because I've never really done a job of this scope before, I'm not sure what to charge for the work. The deadline is very tight - they're looking for a one week turnaround. Can anyone out there give me an idea of what would be fair and realistic to charge for this kind of work? Do I charge hourly? Do I charge a set rate? I don't want to overprice or underprice myself.
