I see your second and third points being issues locally as well – if you work for the government. However, you might be interested to know that the most successful business in my neighbourhood actually operates an online high school.

The first point probably depends on your business skills. However, seeing how well that aforementioned business in my neighbourhood is doing, the potential upside is huge.
