If you are running just a small business like mowing lawns, selling food at a farmers market, etc., then that's easy. Just use a mobile wallet and set up a big sign saying 5% off for payments in Bitcoin. If you are looking for a job then https://stacker.news/~jobs is the best place to look.

There are also a ton of links to good sights here, although some of them are more useful than others. My favorite ones I found were the myriad of bug bounties, and Bitcoin Magazine's rewards app.
