Letterhead template

Hi

I am setting up a Nutritional Therapy Business.

I have a logo which I am really pleased with (attached).

I am now looking for a letterhead template to use in Microsoft Word incorporating this branding. It will be used for many company documents such as invoiced and handouts/ recipes.

It must be professional, premium and modern. I ideally would like at least 2 initial concepts.

Thanks,

Steph
