Company letterhead

I'm looking for a modern and minimalistic letterhead design with specific colors and design elements. I need 2-3 variations of the design which will serve as the official letterhead for my company. I have a clear idea of what I'm looking for and my expectations are high, so attention to detail is a must. It should be professional and stylish, making a great first impression to anyone that receives company communications. If you think you're the right person for this project, let's get started!
