Designing Logo, Businees Card, Letterhead and Envelope

I am looking to have a brand mark logo, business card, letterhead, and envelope designed. I do not have an existing logo, nor any specific colors that need to be used; so I'm open to suggestions. But I am attaching a file from which the logo should be inspired. The materials I am looking for to be designed include a brand mark logo, business card, letterhead, and envelope. This project will require creativity and expertise in the field of logo and design to ensure the highest quality product.
