|Alad this should have been part of what's called a business plan. In order to know what you would charge you need to factor many things, cost of equipment, education, salaries, medical insurance....the list goes on. You are in business to make money and should know what your cost to produce the first widget is. Without it, you're better off throwing darts at a board. What it costs me is going to be different that what it cost you and likewise fees are going to be different.
