A website that is easy for me to upload content

I work in the live event industry producing show visuals and I want to showcase my work-photos, videos, client testimonials, technical page listing equipment.I want to be able to easily upload and change content as I finish projects. It has to be cool and have impact. The front page should have a device to show projects which clients can click on.I specialise in widescreen displays for fashion shows, awards shows etc. It should be image heavy with text that appears if client points to image/video.
