Hello. I am in need of a scraper expert who is also able to build a robust Discord system to manage said data and alert users based on keywords.

In a very niche market where websites are relatively easy to scrape. 10-25 retail sites. 6-7 P2P and forum sites.

Product must be serviceable with bot health systems.

Scraper should gather and alert on:
- retail site in stock as it comes up
- P2P product descriptions, price, preview, etc
- keyword updatable
- scalable with users
- discord and/or signal integration
- minimal monthly cost
- local computer host. (No droplet)

Ideal Skills and Experience:
- Proficiency in web scraping tools (e.g., BeautifulSoup, Scrapy)
