These are pretty much outdated questions, while Fiverr is meant to be a $5 gig hiring platform many freelancers in this platform are open to negotiation and many of them have actually figured out ways to get a hook for $5 but then require additional fees for the actual delivery of the complete project you are looking for. Many services there are no long just 5 dollars and you may end up paying more. With that said, there is a reason why Fiverr is still very popular and that is that there is no real comparable platform out there where you can source cheap gigs. You can try using sites like Quora, Craigslist, Facebook groups, etc. but you have to do the manual search and data entry yourself and still may find no takers.
I have hired freelancers from Fiverr in the past and the outcome has been really good. There is this mistaken idealogy that people get what they pay for and while sometimes that's true, its seems more and more (I have launcheds several successful companies and worked with hundreds of other companies) that the idea of 'getting what you pay for' is nothing but an excuse for trying to get away with crappy effort. There are many successful companies and startups who leverage the free or low low cost business model while delivering the highest of possible values to the user. There is also a widely practiced methodology called Blue Ocean Strategy (I practice it for www.Unthink.me) where the point of the practice is to find the most efficient ways to compete, operate and deliver so that over time the company that employs this strategy is able to offer what is called "value innovation" = offer way more than the perceived comparable cost and value for less money.
