Looking for a Freelancer to Design App Preview & Promo Screens

I’m looking for a skilled freelancer who can design a high-quality app preview for my mobile app Vocademy.

The work includes:
• Designing clean, modern app preview screens
• Creating a Play Store / App Store style preview
• short promo video / animated mockups

The app is education-focused, so a minimal, professional UI aesthetic is important.

Please share your portfolio, past app previews, and pricing.
