The only thing that could be more desired is a faster turn around time, although I'm not willing to pay 10 times the amount that this is estimating.
I don't think you are giving me the same low fiverr price, considering the estimate I had yesterday was in the $45 range for my sample script...
There's a massive difference between highlighting your USP and insulting your competitors.
Fiverr is not a direct competitor either, you can get all sorts of things there apart from voiceovers, for example you can get book covers, video recordings of people writing whatever you want on their body, pictures of your logo in front of the taj mahal... its quite cool.
I'd much rather spend two days hooking up the API so that this is entirely self-serve for my customers.
