I'm not sure what you mean when you say there is no easy solution... procure a small vm on Linode or your choice of provider for like $20/mo. SSH into it, set up the crontab to run your web scraping script. I could literally have that set up and running in 15 minutes flat.
EDIT: after reading the other solutions in this thread I'm blown away by how much people are over thinking and over engineering this. KISS people.
