Hi Miguel, Congrats on the new girl!
I know exactly where your coming from on having things custom made and put together to make it what you want. The times I have done that going into the project it looked cheaper on paper but by the time we were done it was the same price if not just a little bit cheaper or more than going with a full kit made for it and already all the bugs & kinks worked out and the kit would include a warranty and THEY would install it. Then the ongoing headaches for something that is better but not quite right, the boat is my place to get away from all of life's hassles.
Just my opinion, but good luck with the project and happy wife happy life always rings true!
