I just completed a standee that took 4 times the amount of time they quoted me, even with assistance. After they ignored and avoided me during my last assignment, I think this ends my time with this particular company. I've got a lot more complaints, as well, but perhaps that's best for another thread.
Point is, for all of the pain that these are to complete (literally! my fingers are still numb), I'm not trusting them to be forthcoming about the amount of time these take, or the pay for my time anymore. Do not recommend.
