Add new question to the seller

Dear sells representative... I have questions. In your estimation, what will it cost to complete the following work on this 1994 Crownline 225 BR 7.4 liter Merc Cruiser? Is it something you could complete in house?
1. replace all rotted flooring with new factory marine grade wood & install new carpeting
2. rebuild and reupholster with new uv resistant vinyl materials plus cushioning all seating front to back (bow & cockpit)
3. rebuild or replace all mechanical parts for steering, gear shifting & throttle controls for positive smooth operation
4. rebuild the engine & bravo one lower drive unit to make it sea worthy enough to travel 115 nautical miles on open fresh water?
My interest is peaked because I purchased this same Crownline model new in 1994. It would bring back many enjoyable memories.
