One of my specialties is academic editing–it probably helps that I’ve been helping Micah with his papers since we were first dating. Right now I’m working on his dissertation and was joking with him that I should charge for my services. But since our finances are merged, that wouldn’t really work. So he’s paying me in back and footrubs.
Whether you’re a freelancer or homemaker or salaried employee (or other), you likely have skills you could charge for. Maybe you make nice baby quilts. Or perhaps you’re really good at fixing peoples computers or helping them with CSS (shout out to Gibble!).
I don’t charge Micah (really, though, I should come up with backrub invoices) or some of the people I’m closest to. I also give away some of my sewing services as a volunteer. One problem with becoming a legitimate freelancer is that in college I would pretty much edit for anyone. And other English majors/friends would return the favor—which was a kind of payment.
As a skilled individual, one of the things you need to figure out is who you charge, who gets discounts, and who gets it for free.
Who gets your services for free? Who has to pay? Who gets discounts?
