Tri-Fold Flyer Design Needed

I need an eye-catching A4 tri-fold flyer that promotes my windows and doors sales service. The piece has one core job: convince readers that choosing our products will boost energy savings and insulation—those benefits must stand out instantly. All copy, logos, and high-resolution photos are ready on my side, so you can focus on layout, typography, and a professional look that aligns with home-improvement branding. Please build the artwork to standard print bleed specifications and deliver it both as a press-ready PDF and an editable file (AI, INDD, or layered PSD—whichever you prefer). I’ll review a first draft for structure and visual direction, then one revision round should finish it off. Let me know if you need any other assets or style guidelines when you start.
