I’ve used Fiverr for many different services: logo, ebook formatting, graphic arts, professional testimonials, website development. For the most part, I’ve had a good experience.
There are some things that consistently are irritating to me, however.
Not being clear about what your service is, and how much it will cost. I find over and over and over, some list a service for $20 or $50 then all of a sudden, I get an order for $200. It’s why I always try to get clarity on scope and pricing. Most likely, if you do not state exactly what I’m getting and for what price, I will walk away from you. It’s bad business.
Professional testimonials: two times I’ve used Doctors to review clinical studies and provide opinions I could use. Both times, the Doctors were not doctors or were not affiliated with the medical institution it clearly stated in their profile. Understand if you do this, not only are you a crook, but you bring legal liability to those of us that use your information. This is beyond non-professional. Fiverr buyers beware. Check out professional credentials THOROUGHLY before you hire a licensed professional for anything.
those are the biggies. Bad business practices make those of us who would employ you want to not come here. And a few bad apples amongst you ruins it for the rest of you who are solid.
