seeking graphic designer to modify an existing logo for screenprinting

Hello! Seeking a skilled graphic designer/illustrator to execute an idea I have that is based on an existing logo. Essentially, I am looking to modify this existing logo to my specifications. I will require a finished file of the whole logo with a clear background, as well as layered files by colour (for use in a screenprinting context). Finished file must be high resolution - 300 dpi or higher, and preferred formats for layer preparation: PSD, PDF, AI, JPEG or EPS. If you have experience with design for screenprinting thats an asset.
