I think this could be a really interesting project as it transfers across all sectors and it's scalable. Imagine you need a little bit of temporary advice as to how to set up a social media marketing plan, you've got an expert waiting for you on the phone. How about you're fixing your sink and get stuck, there's an expert waiting on the line to talk you through it. It definitely ties into the gig economy like mechanical turks too but the question is whether the "experts" will get paid a fair fee and how that filters through to the end user.
