I am interested in the list of contacts to companies creating high
quality custom
fonts for corporate use. How long does it take to get new custom font
family (regular, italic, bold, bold italic)? There are two basic types
of custom corporate fonts: absolutely new typeface, and modified
existing typeface. What is the the ratio: what clients of
type foundries prefer? How much is new font family and how much is
modified family? 
And finally, what are the main reasons to get custom corporate font,
when there are already so many type faces.
