I will pay you 50 usd to upload a video i will provide to the ios game store and the google play game store. But the 2 most important things are #1 the resolution must be 1080p. and #2 the video must be made to work on the various different screen sizes. You must complete these 2 for the job to be considered a success.
Again payment for this job is 50 usd. If you want to bid more you can but you simply wont get the job. Realistically it should take only 15-20 minutes to complete.
