Progress has been made! After mangling the insert frames with some less-than-sharp-and-intact borrowed snips, I managed to break my drill bit on a bit of steel embedded in the window jamb ceiling. Luckily my Father the Carpenter saved the day.
Evidently you can charge pretty much whatever you want on Fiverr nowadays. I've heard enough hullabaloo around the internet about people making most of their VO income from tons of short, sweet, low-paying gigs from Fiverr, and from looking at some of the profiles on there, it definitely looks to be working for some folk.
