Korn Shell query...is there any source or compiled versions?

[Axel Virgo]

As the keywords indicate, I'm on a mission to find a company(ies) that
sell license for source to Korn shell or a pre-compiled version of
Korn shell. 

It's for our educational institution so we aren't really looking for WAY out
prices to be quoted here, but if you have any information or are a seller
of such product, please e-mail me details(prices,etc.).

Thanks in advance,

Paul "Axel" Virgo
