I would consider using a naked µC instead of an Arduino board. Because
is is typically much cheaper.

The method you used for 1 board works for 1000 boards as well. It just
takes more time.
If you decide for a naked µC on it's own board, you will probably have
it manufactured by someone. Most board manufacturers also offer the
service to flash a program of your choice.
