Shopify Landing Page Design and Developer

Hi! I need help with a Shopify design project

Project: 1 "Coming Soon" landing page on Shopify
Brand: Premium children's brand — minimal, elevated (not cartoonish)
Deliverables: Hero section, brand message, email capture — mobile-first
Scope: Design + implementation + 2 rounds of revisions
Note: No product photos, brand kit in progress — design carries the page

Can you provide:
1. Is this straightforward for you?
2. Fixed quote for $200
3. Estimated timeline

Need this ASAP!
