Custom Website Development Needed

I have complete frontend (HTML/CSS/JS) and backend (Node.js + Express) code for a stock market AI ideas website with login.
I need someone to:

Deploy the backend to a paid host (like Render / Railway / VPS / cPanel Node support).

Set up MongoDB (Atlas or any managed DB) and connect it.

Configure Upstox API with my access token for live NSE/BSE data.

Configure Gemini AI API key for research & rationale generation.

Connect the frontend to the deployed backend API.

Add my custom domain and SSL.
I do not want to touch code or servers myself. Just take my existing code and make it live, fully working, and give me login credentials for admin.
