Call me old fashioned or whatever you may but I cannot believe the number of wannabes setting up a business without doing basic market research such as pricing structures. If you don't know what to charge see someone with the professional qualifications to advise you or do your OWN research. In all my years as a photographer, accountant, printing company director, tennis coach to name but a few of my ventures I have never had to publicly ask what to charge. These are business basics & if you do not have any idea what this entails find another vocation. Sorry to sound so harsh but I expect payment for my professional advice just as many photographers will not give away their work.
