Sophisticated Coming-Soon Instagram Graphic

I need a single, polished “coming soon” image to hold my brand’s Instagram space until launch. The vibe must feel elegant and sophisticated: a clean white and black foundation with just a touch of turquoise for accent. My logo and a short teaser line (which I’ll supply) sit at the center of the design, so balance and negative space are important.

When you deliver, I’d like:
• A 1080 × 1080 px version for the feed
• A 1080 × 1920 px story version
• The layered, editable source file (PSD or AI)

I’ll pass over logo assets, fonts, and copy as soon as we start. A quick turnaround within a couple of days would be ideal, and examples of similar launch placeholders you’ve created will help me choose the right designer.
