My brother built a wedding photography business in ~2008. He filled out the entire first summer of bookings with $50 of highly targeted facebook ads (female, engaged, 200mi radius).

The same ads today would be much more competitive, but there's a huge amount of leverage here.

Facebook ads were so underpriced for a while, you could get 10x ROI. Nowadays you get what you pay for.
