Claude Cowork skill for lead collection

I'm looking for a developer to build a custom, reusable Claude Cowork Skill for automated B2B lead generation. The user provides a city and industry, and the AI agent retrieves company information from a public API, finds company websites, extracts email addresses and phone numbers, and saves the results to Google Sheets. Required skills: - Experience building custom Claude Cowork Skills and AI agents - Python, REST APIs, and JSON - Web scraping (company websites) - Google Sheets integration - Experience optimizing AI workflows to minimize token usage and costs The solution must be portable between Claude accounts and work without paid third-party services, external hosting, or a separate Claude API subscription. Please include examples of relevant Claude Cowork Skills or AI agent projects you've built.
