At this point we only require a new logo.

prefer something with a little red, black, silver, charcoal and white (but definitely open to other ideas - so don't stick with this). contempoary. fine lines, circles ok - no 'fluff'.

We haven't branded before so can't provide any old materials.

After we decide on our new branding we'll be building a new website and will be looking for designs for this as well.
