Extend the post written by date author with more fields

Hi!

To start with, scripting has not been my best on websites – though i can do things.

i’m looking for a solution (been looking though lots of plugins with no luck) that can edit the “entry-meta” for the post author on posts.

Now the below is shown in the post top as author:

e.g.: This is posted on %date% by %author%

I wonder if it is possible to change this to add custom fields for each author to fit the below variables

%TITLE%, %COMPANY%, %OFFICE%.

So whenever a user post a new item on our blog, the line:

“%date%, %year% by: %author%, %title%, %company%, %office location%”

so above would be printed as below, taken from the user profiles inserted data:
