Hello Sir,
I am a PhaserJS based HTML5 game developer who specializes in making playable advertisements. I am in this for past 2.5 years and have made over 100 playables till now.
I can make builds for following platforms currenty: Facebook, Ironsource, Applovin, Adcolony, Unity, Tapjoy, Lifestreet, Google Adwords, Google Doubleclick, Vungle. I can easily add new platforms if you need.
Due to client policy, I cant share you links of playables. I will see how I can send screenshots. I normally work on Upwork so my experience of freelancer is pretty new.
Depending on complexity, it takes anywhere from 3 to 6 days to finish a playable after its finalized and charges are around 250$ to 600$, which will also again depend on complexity.
All the playables I make are fully responsive and work on all aspect ratio devices.
I understand you will provide all the graphics, sounds, intro and end card. Thats great besides that we will follow gameplay, although sometimes I might suggest you to do some things differently if you are interested.
