[The process of selling Private Region: links to visuals]

I'm starting the process of selling a private region.  I'm to the point where I understand a concierge third-party observer to the transaction is required (good so far - witness to proper takeover of billing).  What I'm searching for is a link to examples of what the back-and-forth actually looks like on (digital) paper. I want to feel more confident about all the steps beforehand and looking over a transaction - I'm not finding anything that would help me in such a literal/visual way.  If anyone feels inclined to share a transaction experience "paper trail" or lead me to better links than I've found so far, It would be appreciated.  

Thank you to anyone who responds in advance.

I need to submit some information found in my chat log records to document a malfunction. Where do I find them?
