If you Google 'DF Sponsorship' you can get all the info (&rates). I believe a weekly sponsorship is about $13k and he does $15k-20k per podcast across 3-4 ad reads.

It's 9K. I really wish you'd Google'd that yourself. I have no idea about the podcasts.

There are ads from The Deck (which is a semi exclusive advertising network) on the sidebar.
