Modern 1200x600 Sale Banner Design

I need a sleek, modern product banner sized exactly 1200 × 600 px that spotlights an upcoming sale on my website. The design should immediately communicate the promotion with bold, on-brand colors, clean typography and an obvious call-to-action. Please work within that single fixed dimension so the banner drops straight into my hero section without cropping.

Here’s what I’d like from you:
• Two initial creative concepts in a modern style for me to choose from.
• One refinement round on the chosen concept.
• Final deliverables in a web-ready PNG or JPG along with the fully editable source file (PSD, AI or layered PDF—whichever you create in) so I can tweak text later.

I’ll supply logo, brand colors and sale copy as soon as we start. Let me know if you need anything else to move forward.
