I do not want to imagine how much the navy is going to cost. The Confederacy even in the best possible scenario is going to have to build it from scratch (or what survived the war), including a lot of naval infrastructure.
I'd say a 25-40 million might be a good ballpark figure for a basic fleet (without counting personell,) including some harbor fortifications. Since places like Charleston, Corpus Christi, Jacksonville, Savanna, Pensacola (or Mobile) and Cedar Key would need new facilities built to support the fleet, as the CSA would likely only have New Orleans and Norfolk Naval Yard/Gosport Shipyard, and the latter of the two might be in pretty bad shape.
That project by itself would easily be a multi-million dollar ongoing headache (, while a simple Fourth or Fifth-rate Frigate, without any armor would be something like £250k after being fully fitted out, and a modern ironclad was something like £260k (HMS Resistance) up to about £350-370k (HMS Bellerophon) being the norm for an Ironclad of the period. So, half a million to a million CS dollars per ship, assuming run-away inflation hadn't completely fucked the value of the CS Dollar (ASB, I know.)
