So, my free to play (and no ads!) mobile party game Gimme That Thing has just come out on

iOS (Gimme That Thing! on the App Store)

and Google Play (Gimme That Thing - Party Game – Google Play)

and I'm looking to pay some YouTubers with a medium sized but engaged audience or ‘micro influencers’ as I believe they are sometimes called, to play it and show it off a bit.

My question is, is there a hub like Fiverr (because there's not many on Fiverr) of guys and gals who offer this service. Is there a ‘gaming streamers who will play your game for a fee’ website? If not, how do you generally go about finding people offering this service, short of spamming people on YouTube?

Any advice, warmly received!
