The logo needs to between 1400x1400 and 3000x3000.  The closer to 3000x3000 the better.  .jpg  &amp;lt;500 KB file size.  That is the size that iTunes requires.  I would like to be able to make it somewhat larger for other things if needed.  
It might say, "The Real Estate Syndication Show with Whitney Sewell."  You figure out how to lay it out.  
I was not really sure what logos to pick as samples.  It needs to be easy to read and bold.  Solid background.  The parent company logo is attached.  You could use the same colors or incorporate them somehow.  Just a thought, not a must.  

Ingepro was great!  Made requested changes fast and communicated well.  Great Logo!
