Hi, I'm used to work with wordpress, and create a really simple content maneger with this plataform.
Trought my skills, I can create something that will fullfill your needs when managing the contents of your website, you gonna be capable of post any kind of media, images, videos, audio, from youtube, vimeo, soundcloud etc... I also could give you full support and a tutorial to use the website created.
If you interested I can talk with you via skype and show some of my work. :D
cya!
