Help solving a issue and building Unity 2017.2 3d project to Android SDK

I did a AR game using Artoolkit in Unity 2017, It plays perfect inside Unity, all the markers are recognized and the videos, images and sounds works perfectly, but I cannot build it to Android SDK. There is a issue building Unity 3d to Android SDK that I cannot solve.. I need a freelancer who works with Unity 2017 and are building to Android with success. I will send the package to the freelancer and I expect that he does for me the last step that is to check if the project settings are OK and to build to Android. Work plan: 1- check if the settings are OK and if it is possible to reduce the file size of the build as much as possible in a way that the images, videos and sound have nice quality. 2- build for Android. 3- send me it to test. 4- do the necessary adjustments (objects position, rotation, scale), 5-send me the final build, 6-send me the Unity package 7 - give me some advise in free AR softwares for my future projects. If we work well together I want to develop more games in the next future. Attention - this project must be completed in 24 hours. I need an expert in Unity 3d and Android SDK integration. If you have no experience in this, please do not bid.
