There is no sin in providing great camera work and letting someone else do the rest.

I'm not so sure about that - If you allow the client to print, and this is done poorly, then this can, at best, take away the impact of a great shot, but at worse give prospective clients a poor impression of your work.

I can understand being protectionist about who handles / prints the negatives / files. Plenty of photographera will only supply a finished album or framed prints.
