Lancaster, PA resident here. Many, possibly most, Amish are not farmers anymore. To your point, a lot own businesses like lawn care, grocery and hardware stores, tourist traps, and construction companies.
Since childcare is mentioned, I would be remiss if I did not point out that the Amish have a disproportionate rate of child sex abuse. Offenders often get off because the Amish community pressures victims not to testify. Victims are sent to re-education centers. It is pretty gross what goes on in plain (pardon the pun) sight. But they bring in tourist dollars. Most Amish are lovely of course, but their lifestyle has a very dark side.
