I need a Podcasting Professional

I am going to be hosting a show about facts, those of a more bizarre and niche nature. I have not yet settled on a name for the podcast, so I would like some assistance with that. I also would like a professionally made cover art as well. Some episodes will be straightforward facts, others I will read out and compare to human behaviour if they are about animals. I will have comedy throughout, probably quite dark comedy. Some of the facts will be about rock, grunge and heavy metal music.
