Hi....It cost 1500 pesos....which is about the going rate for all tattooists.
I called in at the beginning of my holiday to make an appointment and tell him what I wanted...he drew a rough sketch to which I agreed...then went back to get the finished design done a week later. So I don't know for sure how long it took him...my guess is about 30 mins! The tattoo took about 45 minutes. If you're getting one done, schedule it for the day before you leave for home as they need to be protected from sun/sea etc.
Sorry for the delay in replying...I never noticed the 'message' sign (Doh!)
