Corporate E-Commerce WordPress Site

I need a clean, professional WordPress build that positions my HR Tech company as a trustworthy brand while letting visitors purchase directly on-site. The site’s core is a corporate-style storefront, so good information architecture and polished design matter as much as smooth checkout flow.

I've started the site using a selected SaaS WordPress theme I like, but open to changing.

Here is what has to be in place before hand-over:

• Product catalog organised by category and searchable
• Fully integrated payment gateway (credit/debit cards plus PayPal or Stripe) tested in sandbox and live modes
• Dedicated “Features” section to highlight key product benefits
• Blog area set up with at least one sample post so my team can see the workflow
• Products page displaying individual items and an additional pricing table that compares Package A, B and C side by side (already drafted in a SaaS WordPress theme)
• Contact-us page with embedded form, Google Map and clickable phone/email
• Mobile-first responsiveness, SSL, speed optimisation and basic on-page SEO (permalinks, meta titles, alt tags)

I work from brand guidelines and will supply logo, palette and copy; you handle theme selection or a lightweight custom theme, required plugins and any minor CSS tweaks. Elementor, Gutenberg or another modern builder is fine as long as the final site is easy for a non-developer to maintain.

Please confirm estimated timeline, the WordPress tools you plan to use and any past corporate e-commerce examples you can show.

Initial help needed to get the site ready in next 30 days for market launch.
