Studio Announcements

I've never sold direct, always through a third party, so I'm pretty new to this stuff.

-- What kinds of payments do you guys accept? Cash/checks/money transfer apps? Are there some apps that are better/more secure?

-- Do you have business cards? What do you add to the cards?

-- I have instagram, but rarely use it. Is it useful to add all my pieces and use it as a point of contact?

-- Should I get a dedicated email address or phone number?

Thanks!
