So people could like something like I will do x for you for $y amount, all I need is you to fill out this template / give me this info.
So automate it as much as possible, and know how much it would cost. Break big tasks down into small ones.
For example, someone may offer to find you the cheapest place to buy tires in your area. All they need is <city>, <any necessary details on tires>.
Something like that.
What is wrong with using taskrabbit itself? What tasks do you envision? What about virtual assistants like Zirtual.com?
I don't want to negotiate, I want a quote and a yes/no decision on the quote. That's it. Period. End of story.
--- has tried to use TaskRabbit on three different occasions to get something done, all failed, two were to get lunch for an office. (so, business)
Never using TaskRabbit again.
I don't know enough about businesses to know what sorts of tasks would be good for this.
