For hard standing you really can't beat Bruces in Faro, we wouldn't go anywhere else. If you need work doing you are probably better off in Lagos or Portimao. Be warned though there is one firm here that I wouldn't touch with a barge pole, but i think they are not allowed to work in Sopromar (lagos boatyard) anyway. Be careful and ask people that have been around the area for a few years. When people overwinter and move on the cowboys have a fresh batch of people to prey on - just because an outfit looks professional doesn't mean they are. The Algarve is brilliant though, and i'm sure you'll have a great time.
