David Blevins of Perfection Group holds a sample window for the Clinton County Commissioners’ review Monday. Sitting near him are Tony Apro, CEO of Perfection Group, and County Administrator Mary Ann Foland. The commissioners approved a $5.2 million contract with Perfection Group for renovations to the Clinton County courthouse. Now, the commissioners must decide if they’d rather pay for it up front or finance it and use the deferred capital to draw investment earnings.
