Automated Product Scraper & Uploader

I need a small application that watches a fixed list of supplier sites and, whenever a new item appears or an existing one changes, pulls the full product details, prices, and images, then pushes everything straight into Jamex.co.jp so the listing goes live immediately without manual review... (Budget: $30 - $250 USD, Jobs: API, Automation, Data Extraction, Data Processing, PHP, Software Architecture, Web Scraping)
