B2B Supplier Directory Website

I’m building an online directory whose main role is to connect businesses with the suppliers they need. The platform must allow two distinct user groups—companies looking for products or services and suppliers offering them—to register, create secure log-ins, and manage their own profiles.

Core functionality I expect:
• A robust, searchable supplier database so buyers can quickly filter and find matches by industry, location, or keyword.
• Embedded supplier contact forms that capture enquiries and route them to the correct account.
• A direct, in-platform messaging system so both sides can discuss terms without leaving the site.

I’m open to the stack you prefer, as long as the solution scales and keeps page-load times tight. Clean, modern UI/UX and responsive design for desktop and mobile are essential. Please outline your approach, preferred technologies, any similar directories you’ve launched, and the timeline you foresee from kickoff to go-live.
