High-Resolution Landscape Sign Design

I need a professional designer to create a high-resolution (300dpi) image file suitable for printing a landscape sign approximately A1 in size. I will provide a small concept file in PNG format that you can use as a reference. The design must be created in vector format for scalability, and I will provide specific branding guidelines and color specifications to follow. Ideal skills include experience in graphic design, proficiency in design software like Adobe Illustrator, and the ability to work with branding requirements.
