Ask HN: Crowdsourced travel sites? (similar to 99designs or Flightfox)

I'm trying to plan a trip to Japan and wanted some kind of site to plan out the entire thing for me in return for some kind of finder's fee. I found this project by FlightFox (https://flightfox.com/trips/crowd-sourced-vacation) and was wondering if there were any.

For reference: flying to Japan (start or end in either Tokyo or Kyoto [Osaka]), cheap-o in Tokyo (sub $60/night) and can go premium in Kyoto or Hakone along the way (~$200-$300/night). 6-9 nights. Budget is around $1500 to $2500 for 2 people inclusive of food/lodging.
