Can you ask Amish people to build things for you?

In Fremont MI there is an Amish community. Is it acceptable to ask them to build things for me? The local businesses advertise quite a bit that they have "Amish made-" this or that. But can I just ask someone in the Amish community directly? (would prefer an answer from anyone who knows of the Fremont MI Amish community, but all answers will be appreciated)
