Ok this is a two fold question I am just throwing out there! 1: If you (like nearly everyone when starting out) underpriced a client, that keeps bringing reasonable work. How do you transition for undercharging him to charging enough without losing him, or making him refuse to pay because all of a sudden your 5-6 times more expensive. 2. I used a cost per day estimator which takes into account your area, age, experience and it said I should charge 200£ a day. This seems a lot to ask for. For example I recently done a 36 page product brochure and it took 5 days work. That would be 1000. That seems a lot to be asking a client for who is probably expecting a 100-200 bill.
