Replying to Starting wage for skilled worker

Okay, so I am going into a job interview this morning at a local screen printer and embroiderer in Boston. I have owned and operated my own manual silk screen press for about three years now. I am qualified, and experienced in this subject. They will be training me on an M&R Gauntlet automatic system. "Pay is based off of experience". Because I am familiar with the screen printing industry and they "would be willing to train the right person who has manual screen printing experience", and not have to train me on all the other aspects of the business(clean up, dealing with chemicals, cleaning and prepping screen, prepping emulsion, exposing images, ext.). what should I ask for a starting wage?
what was your starting wage for the career you have been training in for years?
any insight helps, thanks all.
