Need help for a project.

Hello, So I wanted to make a website kinda like a directory with thousands or hundreds of clothing companies with certain roles of employees listed. Mainly focused on the textiles/apparel business. Helping textiles companies or buying houses find buyers easily. Now putting in the contact details of employees is doable manually but It will take a lot of time. and I have never done web scraping or crawling before. So any tips would help to accomplish this. Thank You.
