Hi I've bn 2 Ibiza twice on holiday and met sum ppl who wrkd there for the summer, they said the best thing 2 do is 2 get out there late April or early May and just ask araound in all the bars!!
They also said 2 go 2 a pub called the ship, which is near the westend, they have jobs and accomadation on a noticeboard on a wall on te left as u walk in!!
Hope thats a help 2 u!!
