As a freelancer on the site, I can't recommend it. Infact I honest suggest you avoid this site like the plague.
They have THE WORST customer service ever and as you know, if you're trying to conduct a business you need proper customer service. Fiverr have perhaps 3-4 staff working on support (and this is for a site that supposedly has hundreds of thousands of transactions every day).
As a level 2 (which you attain after completing 50 orders) you are meant to get Priority Support. You don't. This is an outright lie.
You get the same support as when you first start on the site - That is, you're lucky to get a response within 4-5 days. When they do respond, it's often canned answers.
They refund buyers without consulting with the seller or even reviewing the cases properly thus offering ZERO protection for freelancers on the site.
So all that hard work you do and then get paid for? A few days, week, month or even 6 months later... The payment you received can be returned to the buyer no questions asked leaving you out of pocket.
When making modifications to your gigs - I added a header graphic to one of my gigs (they keep telling you do to it as they claim it improves conversions). It took TEN DAYS for them to approve the graphic! TEN DAYS.
Moral of the story is this - You get peanuts for the work you do and even those peanuts can be taken from you without question. You won't get support, you're on your own and at the mercy of the buyers.
Try proper freelancing websites then support the Freelancers as priority.
