Hello,
I'm an Unity3d expert with more than 3 years experience in developing mobile applications and games using Unity3D.
I also own an ios device (iPhone 6s plus) and android devices (galaxy s6 plus, nexus 5, nexus 7 and galaxy tab2) for testing.
I need more details to can set a better price.
Let me know if you have any question.
Best Regards,
Nechifor Marian
