Finance Portal Website & SEO -- 2

I need to get a professional finance-focused website live very quickly and have it launch with solid, search-friendly foundations. The public pages will present my services, articles and contact routes. Behind that, a secure client portal must let registered users manage their account details and exchange documents with me—uploading and downloading files through an encrypted channel.

My priorities are:
• Trustworthy, responsive design that looks sharp on desktop and mobile
• A client portal offering account management plus document upload/download
• Clean code, SSL, and all the on-page SEO basics in place (schema, meta tags, XML sitemap, robots.txt, Search Console submission)

I’m flexible on the stack—WordPress with carefully chosen plugins, Laravel, or another framework you recommend—as long as the portal is bullet-proof and the admin area is straightforward for me to update.

Deliverables
1. Fully deployed finance website on my hosting
2. Secure portal with account and document features working end-to-end
3. Initial on-page SEO rollout
4. Short hand-over guide covering updates and backups

Let me know the tools you’ll use, any licences or APIs required, and, most importantly, how fast you can have a first working version online.
