I actually signed up for timesvr earlier tonight after reading this. They claim $59 a month buys you unlimited tasks, which I cannot believe is profitable, but if they can make money off of my business, I wish them health and happiness.
I'm pretty surprised by it as well. The 1 week free trial is awesome too - worst case, you have a team of assistants to do free work for you and you leave after 7 days. Although at their prices, that's really only a $15 free trial so it's not really going to hurt them any
It is surprising that this can be profitable, but if you value your time at anything above $20/hr and this saves you a few hours a week, this is certainly worth it to you if the work done is at a high enough quality level.
