so can anyone give me a rough estimate on how much it may cost to do what i want

just call dave at 419-562-1989 he will tell you , maybe send him some pics of your boat and tell him what you want . he will do the rest . he did this with me and then did extra at no cost . my only regret is that I only gave them a $100 tip to take the team to lunch with . my bad . Tim

Cockpit only, cabin only or both???

If both, I would budget somewhere in the 20K range.
