Yes, definitely follow this advice. Giulietta is your man for a refit in Portugal. He is very knowledgeable and is plugged-in to the boatbuilding and sailing community in your area.I suggest you send a PM (private mail) to Giulietta on this set of forums. He is very knowledgeable about boat construction, and he lives in Lisbon.
Your list is a very ambitious one, especially if you have to pay for all of this work.
Good luck ..
