I have seven years experience on both developer, team leader, architecture design and project manager positions. I also have a senior team can work with .NET, NoSql, PHP, Mobile (ios and android).
I have experience on using ffmpeg tool to merge/ add effect/ modify video, sound, etc...
So I think I can add intro and outro to your video very quickly. And I can give you ffmpeq code so you can do it yourself (plus some sweet :D)
