Hey guys

I'm hoping to run a victory at sea campaign with a friend of mine. But to make things a little different I thought it would be fun to design and build up our own fleets and then play through an 1850-modern day scenario. Obviously keeping an eye on your fleet and budget and maintenance costs etc would be a pain in the nethers so I was wondering if any of the genius type folks here had any advice on how to manage it? If anyone has any applicable rules, or spreadsheets or advice it would be gladly accepted
