Hi Tony,
One particular card i can recommend at the moment, (well its good for us) is the nectar american express business card. We got given a good limit to start. You get 1000 nectar points with your first purchase and you earn nectar points every time you use it. These can be spent at sainsburys and other places.
The interest rate is low as well although we pay ours off every month.
