Hi there - I'm the CEO of Gun.io. Shoot me an email at teja[at]gun.io. Our average rates on platform are 10x higher than that. In fact, that's why we started the business.
But there is other coin too, once tried to hire some `solr` experts ($100/hour rate) whom after I asked about some extension development went out of touch (1 agency & 2 contractors). So it can suck on client side too.
