How much is this piece of string going to cost?
There is no hard and fast rule about how much a website will cost. Most companies will dangle the bait of a relatively cheap website which in turn leads to added yearly admin and maintenance costs.
To give you an idea, the lowest cost website in my portfolio cost only £650, and the most expensive website shown cost approx £11500 (which included photography). Me being an advertising photographer for over 20 years means if you need my photographic services when building a website, you get them at a fraction of what they would cost elsewhere.
My aim is to give you as much as possible for your budget. Most individuals websites cost around £1250, whereas companies that need more pages and functionality obviously cost more.
