Logo design for a startup marketing agency

I am looking for a talented designer to create a modern logo for my startup marketing agency. I will provide a specific color palette for the design. The logo should portray the agency essence which I will provide, and I have specific design elements and symbols that I would like incorporated into the logo. The logo will have two formats:
a long format with the full name of the agency and short format with name initials of the agency. The ideal candidate should have experience in creating modern logos and be able to work with my specific design requests.
