Survey Participant Sourcing Assistant - Virtual Web Scraping

I’m launching several research campaigns and need reliable help finding and organising fresh pools of respondents. The main audience I want you to locate is the general public, with a dedicated subset of undergraduate students for one comparative study. All of the participants you gather will ultimately feed into online survey forms, so every lead must include a working email or social platform handle suitable for a digital invitation—no phone or face-to-face outreach is required.

Here’s what I expect from you:

• Scrape and research publicly available sources—social media groups, forums, event attendee lists, community directories, student networks, etc.—to build opt-in contact lists.
• Enrich each record with basic demographics (age range, location, education level) so I can filter results quickly.
• Deliver everything in a clean spreadsheet (CSV or Google Sheet), clearly separating the broad general-public pool from the undergraduate subset.
• Provide the source URL or reference for every contact so I can verify authenticity and comply with GDPR/CCPA requirements.

Accuracy matters more than volume; bounced addresses or unverifiable records will be rejected. If you have experience with tools such as Python, BeautifulSoup, Selenium, or Scrapy—and know how to avoid rate limits and captchas—please highlight that when you reply.

i'm looking for someone to support MULTIPLE projects for a long time. But i'm sure you need some metric to form a bid, so please post a bid on your costs for sourcing 1,000 participants.
