Podcasting

Okay, here is my situation... I am running tech for the youth group at my church and each week we are creating a video with the announcements in it. My idea is I want to podcast those so the students can download them in iTunes. Now I have a blog and am using feedburner but I need to find a great hosting company that is free that I can link my files from so it can be downloaded through itunes. does this make sense and does anyone have any good ideas?
