It can be hard to know what to charge as a freelance web developer. You often need to have a good discussion with your client about what it is exactly they are looking for and ensure that you fully understand what is required. If you are not aware of a functionality that they want to include, you could vastly underquote the project and then have to break the news to them later that it was not included in the quote. Website projects vary so much in costs from a few hundred pounds upwards of tens of thousands of pounds. There is no way to give someone a quote for designing and programming a website until you have a detailed brief off them. If you are a relatively small start up business that wants a five page brochure site then you can expect to pay from about £500 up to £3000 depending on if graphics need to be purchased and copy written etc. For an ecommerce site you might expect a range of £2000 up £10000 for a small to medium business.

Be sure to show your client examples of other websites you have done and what sort of thing they can get for their money. Also be sure to clearly explain upfront what they need to do such as provide the content and images.
