You can use Libsyn to host the files and use their feed and blog set
up, if you want. You can then buy a domain name and point it to your
show site at libsyn.
A more complex, but more flexible way is to manage your own website
with wordpress / podpress and use libsyn just to host the files (you
will link to them from your site). With your own site, you will have
much more control, but much more to manage (wordpress updates,
podpress updates, etc...) This will give you more control of your show
site and feed. You point the podpress to the show files hosted at
There is a lot to learn...
