My two cents on . . . business cards
Yes, people still use physical business cards. There are any number of places to design and purchase them, but before doing so you’ll need to have made a bunch of other decisions: business name, domain name, tagline, phone number, logo, email address, and, possibly, snail mail address and social media channels. Fortunately, most of today’s business cards are double-sided, so you’ll have room for all that info. Resist the urge to make business cards before you’ve figured out most of the other details!
And consider putting your head shot on your card – it’s increasingly popular these days if you’re selling a service.
