WordPress to Squarespace & Stripe

I have already built the new Squarespace site and the visual design is locked in. What I need now is a careful, no-downtime migration of everything. The site is already complete. No need to add new design or anything like that.
• All service description pages, keeping current copy and any downloadable assets
• Domain transfer so the live URL flips from WordPress to Squarespace smoothly—no broken links or “site down” gaps

Once the content and domain are in place, I also need Stripe configured inside Squarespace Commerce so that credit-card payments run flawlessly. That includes connecting the live Stripe keys, mapping products to the correct pricing, enabling Apple Pay / Google Pay where possible, and running a test transaction before launch. I already have activated stripe on the squarespace, i just need someone to confirm that the stripe account is right.

Deliverable: a fully live Squarespace site on my domain with every product and service page intact, Stripe payments verified, and a brief hand-off note explaining where to update inventory or pricing in the future.
