Service directory

One page per service, with where its free tier stops, the first paid step and what it costs. The picker reads these same rows, so the two cannot disagree.

A figure marked not checked is one nobody has held up against the vendor's own limits yet; one marked stale was checked more than 90 days ago, and is shown as a date, not as current. Where a service's link carries a referral commission, its page says so; a commission never changes the order here or the picker's answer.
