Plugins/themes for online podcasts with payed video streams via klarna

Can anyone recommend me a template or suggest plugins with which you can implement the following:

  • create graphically beautiful app (template)
  • 8 podcasts category’s
  • free videopodcasts should be offered there via a stable videoplayer
  • individual podcasts should be able to be purchased once and then viewed for free for an unlimited time (video stream)
  • payment by credit card or klarna

I would be very grateful for any tips.
