WordPress-to-XenForo Auto Scraper

I need a small utility that logs in to a private WordPress site with my username and password, pulls each new post’s title, main photo, body text, and any download link, then republishes that material to my XenForo forum through XenForo’s REST API... (Budget: €8 - €30 EUR, Jobs: API Integration, Automation, JavaScript, MySQL, PHP, REST API, WordPress, XenForo)
