I say go for it, but your rate needs to be a bit higher than $20/hr. At 23, you'll gain a lot of valuable experience, mainly organizing your time. Insurance is a MUST, even if you're doing this part time. A few hundred bucks on a GL policy could save you from potentially spending the rest of your life paying off one minor mistake. And we all make mistakes. Some minor, some major. Many years ago, I was working in a condo (tiling a bathroom) when the unlicensed, uninsured 'plumber' the HO hired was sweating pipes and set the unit on fire. A big fire that burned 50% of the 4-unit building. I was uninsured at the time (I was 24-25), and got a GL policy the next day, even though I was doing side-jobs part time. I've never had to ever use it, but I know I have it. Peace of mind.
