Create 3 Clean & Editable After Effects Intro Animations

I’m looking for a skilled After Effects designer to create 3 clean, simple, and fully editable intro animations.

Project details:
• 3 intro animations
• Duration: 5–8 seconds each
• Style:
• Clean & professional
• Minimal, not flashy
• Suitable for a wide range of videos (YouTube, general content, business use)
• Smooth, subtle animation for logo and text
• No third-party plugins (important)

Technical requirements:
• Well-organized, fully editable .aep files
• Easy to:
• Replace logo
• Edit text
• Change colors
• Resolution: 1920×1080
• One version with background + one with transparency
• Clean looping at the beginning and end

Preferred:
• Samples of previous intro / motion graphics work
• Mention of the After Effects version used

Looking forward to your proposals. Thank you
