Brand Identity Package

I’m looking for a designer to help me create a basic but cohesive brand identity for my tech company and adapt it to different products. I mainly need a simple brand guide (logo use, colors, fonts) plus the core assets: a modern, unique logo, a clear color palette with HEX/RGB codes, and suggested fonts. It would be great if you can also prepare some social media templates and simple stationery (letterhead, envelope), and adapt the branding to product applications like packaging, labels, or merchandising. The files should be delivered in editable formats (AI, PSD, Figma or similar), but I don’t need anything overly complex—just clean, consistent, and ready to use. Please share examples of your past work so I can see your style.
