Digital template for letterhead that we can populate ourselves to write any information

We already have a logo which I can provide.
I want the overall look to be smart, professional, sleek but also aesthetic.
Our colour palette is anthracite grey and other neutrals, favouring clay or putty colour. We can use gold as an accent colour.

The logo may be made into a round badge style shape.

We would also like a design for transfer sticker to put onto a gift bag. This would have the logo and similar colour scheme.
