I know money lenders aren't a great category, however, Provident were arguably one of the better ones (slightly). And they have helped people get small loans when often they'd nowhere else to go.

This was a TV ad pitched to them back in 2015. It wasn't successful, but it's just to show the type of ad I can create.
