I don't negotiate prices on my work I don't know the exact situation that you are in but my price is my price. One thing to remember is that offer more on the price which will allow you to have more time to do a better quality job and still make a decent prophetic you charge less you must hurry to make a profit which means that you are more likely to make a mistake and do a poorer quality job so I would ask the customer if they want a poorer quality job or a better quality job I don't negotiate prices on my jobs that I bid if they want a creeper price I politely declined and tell them to go with the cheaper price that someone else offer them.I don't bid my jobs just to get a job if they want it cheaper my price is my price I hope that this will have help you .
