Suggest doing an internet search on boat yards in the Miami and Fort Lauderdale area and find ones that do bottom painting. Some will post their prices by the foot depending on paint type and number of coats.
Do the same for a marine surveyor. Since Covid surveyors are very busy do to the hot boat market. Curious why you want a survey (insurance or marina requirement?) and type of survey...... general marine, hull, rigging, engine, electrical?
