How much would you pay for a custom business card design?

I am starting my own business doing graphic and web design. Most of the work so far that I have done has be for friends, friends of friends.

I just wanted to sound out what most people would expect to pay for a custom designed card, i.e. not a pre made template, but custom designed to meet your own (businesses) needs.

I have had a look about and a lot of UK design palces are charging anywhere between £40/50 up to £80, or even up to £25 per hour spent.

Previously I have charged £30 for a double sided design.

All these prices exclude printing.
