Shopify Store UI Overhaul Needed

My Shopify storefront is live but still running on the default look. I’m adding the products myself; what I need from you is the full visual and structural polish so the shop feels professional and corporate from the moment a visitor lands.

Here’s what I expect you to handle right away:
• Select or customise a theme that matches a clean, corporate aesthetic, then configure it so every core page is consistent in style and mobile-ready.
• Create eye-catching homepage and collection banners (static or simple motion is fine) that reflect our niche and any seasonal offers we’ll run.
• Build a clear collection / category hierarchy so shoppers can browse by product type without confusion.
• Integrate a newsletter sign-up that captures emails in Shopify Email or another free app you recommend, with the form positioned strategically on key pages.

I have no strict brand book, so you’re free to pick fonts, colour palettes and imagery—just keep the overall tone polished and trustworthy. If you know of other no-cost or low-cost apps that improve lead capture, analytics or page speed, suggest and install them as part of the setup.

Once the initial facelift is complete, I intend to keep you on for tweaks, seasonal banner swaps and any future feature builds, so a long-term working relationship is on the table.

Send over a brief outline of how you’ll approach the theme selection, any past Shopify stores that show a similar professional look, and how quickly you can deliver the first version ready for product uploads.
