Ask HN: Outsourcing/contracting in 2018

I'd like to hear about outsourcing experiences of tech founders. Particularly success stories. Most of the existing literature focuses on [negative] experiences of non-technical people.

I often wish you could just easily pay 200-500$/hr to a known developer in a given niche and have them write you a very general outline of how they'd approach a given problem. Wondering if something like this exists.
