Four dollars may not sound like a lot, but if you've got hundreds of people giving you $4, it's gonna add up! This is why you NEED to know about Fiverr if you have any talent... in any area... at all.
Fiverr is an online network where people put things like, "I will promote your product on my blog for $5" or "I will perform a ridiculous and passtionate acapella version of any song under five minutes for $5". You pay $5, the person gets $4, and Fiverr gets $1.
If anything, just go check the site out cause some of them are hilarious!
