Have you actually thought about what you want to earn on an annual basis? I work on a formula of the annual rate, then deduct the hours needed for holiday leave, sick leave, and other items (as in a regular job), then work out the number of hours I would actually be working. You then come out with a basic hourly rate and need to factor in costings for overheads, i.e. your running expenses. This will help you.
