Interactive Procurement Website with Scraping

I’m building a procurement-focused site where buyers can quickly locate and purchase industrial materials. The core of the project is a smart search that reaches beyond an internal catalog: whenever a user enters a product type or key specification, the system should automatically scrape up-to-date information from relevant supplier and manufacturer websites, then display consolidated results in real time.

The scraper needs to collect and store:
• product details and full technical specifications
• current pricing (including tiered or volume-based rates)
• supplier contact information
• compliance or testing certificates
• available volumes / quantities

Filtered and predictive search behaviours (e.g., dynamic suggestions, spec-based faceting) should feel instantaneous to the user even though fresh data is being pulled behind the scenes.

Once a product is selected, the site must support a streamlined checkout with a secure payment gateway. Please factor in typical e-commerce elements such as cart management, tax and shipping calculations, order history and automated email notifications.

Deliverables
1. Responsive web front end (desktop & mobile) with the smart search interface
2. Back-end scraping engine that targets supplier and manufacturer domains and updates the database on a schedule or on-demand query
3. Relational database structure that stores the scraped data and ties it to user orders
4. Payment-processing integration (Stripe, PayPal, or a comparable PCI-compliant solution)
5. Admin dashboard for product data review, manual overrides and order management
6. Deployment documentation and brief hand-off session

Acceptance criteria
• Search returns relevant results in under two seconds for common queries
• Scraper captures 95 %+ of the specified data fields across target sites without breaking layout or ToS rules
• Successful end-to-end purchase flow verified with test payments in both sandbox and live environments
• All source code, instructions and credentials delivered before final sign-off

If you have experience blending real-time web scraping, fast search indexing (Elastic, Solr or similar) and secure payments, I’d like to hear how you’d architect the solution and an estimated timeline.
