It really depends on your area, your skill set, experience and what you have to offer that others in your area may not. Clients will let you know what is too much, as they won’t sign on at that rate. Then again, I find that people are willing to pay more for results, experience and specialty. How do you stand out from your competition? What do you offer your clients that they don’t? How can you communicate that to your potential clients? How do you let them know about your previous successes? All of this communicates to your clients why you should get paid the price you’re asking.
