Where are you located? How many years of experience do you have? What does your competition charge? Is there any competition?
Do you have any pictures of your work?
Generic questions will typically get generic answers, so hopefully you can expound on these questions. I can't recall seeing any of your work, so being able to give you any advice based on your own opinion of yourself will be of little assistance to you. Personally, I'd ask to see pictures of your work before handing over my keys, no matter how great you tell me you are.
Hope to see some pictures and have the above questions answered, and that you get some honest feedback.
