I have a young Senagalese lad that helps me out for four hours a week.  From Spring to Autumn he works on contract Mon - Fri so is only available at weekends.  This time of year he struggles to find enough hours to make a living.  He is an extremely hard worker (will do in 10 mins what would take me an hour) and a very quiet and polite lad.  He can turn his hand to almost anything and is an expert in tending to all aspects of olive and citrus cultivation.
His price is 7 euros/hour.  The only down side is that he doesn't have transport so he would have to be collected and dropped back to Santa Barbara.  I would be prepared to arrange the first visit and introductions within a reasonable radius of Tortosa.  Please pm me if interested.
