I'm always looking for ways to make a little extra money. One site I like is Fiverr. Fiverr is a marketplace where you pay/get paid $5 for small services. There are a lot of creative and silly things you can buy for $5, like having your brand name written on a cake. There's more serious services too, like editing your document or tweeting your business link. You can see Etsy related services on Fiverr here.
I have a good amount of Twitter followers and my service is to tweet whatever link the buyer wants for $5. You can see/buy my service here. I already made $10 there just for tweeting two tweets. The websites were both craft related so I didn't feel like I was spamming for followers and it helped out the people who purchased my service.
I want to think of some other services I can do, but I couldn't think of any good ones that I think people would buy. I'm a Mary Kay consultant and I used to have a service where people could get sent Mary Kay samples for $5, but I didn't get any sales.
Have you ever used Fiverr?
