How much would you charge to make and run a website for a junk yard?

Fall back on the old labor and parts process. Charge for getting a domain name and any other things you need to buy with your money. Then charge for how much your time is worth I would say at least minimum wage in your area. I did charge $100 - $300 depending on what people wanted me to do, but that was a while ago when it was harder to get websites to look certain ways. I aways felt it was a good deal.
