Whales are major projects, such as those illustrated here. Typically they entail the investment of a lot of time and talent, and a lot rests on their success or failure.

Some (eg the Bevan Ashford website) involve an ongoing commitment: we charge a daily rate. Others (eg BT's corporate brochure) are one-offs, for which we quote a fixed fee. In broad terms, you're probably looking at anything from around £5,000 upwards.
