This is a browser extension you can install that will occasionally show you sponsored advertisements on your sidebar when you search. Each advertisement is worth a few cents or more. If you visit the ad shown, you receive the dollar amount shown in your Qmee virtual “piggy bank”. You can cash this out at anytime, there is no minimum. Also, the money shows up in your Paypal account pretty much instantly after you ask for it. I put this site on this list because even though it's not a big earner, you can get paid quickly.
Another survey panel that pays fast, but you do have to have $15 in your account before you can cash out. This can take a while to reach if you don't have a lot of referrals. They are owned by the same people that run Instant Cash Sweepstakes. Typically payment comes to Paypal the same day you request it, although it has taken up to three days before.
Fiverr is a popular platform for offering services. You can create your own Gigs to have available for sale. As the name suggests, Gigs are available to purchase starting at $5 though you can offer upsells to increase your earnings. You do need to wait 14 days between completing a Gig to being able to withdraw your earnings by PayPal. There are fees associated with these transactions.
