Does anyone have contacts, info or ideas regarding finding jobs in Spain?
Apart from teaching English, I would also consider working at a summer camp (I am a swim instructor and yoga teacher) or volunteering, 3h per weekday of teaching English in exchange for board.
I was offered a summer position with Pueblo Ingles a few summers ago. They have summer camps in a few different locations throughout Spain. Unfortunately, I had a conflicting work schedule in Prague at the time and wasn't able to join the camp. Some friends of mine did, however, and they raved about it! It is a volunteer camp and they do provide room, board, and food. You can check out their website, I believe its just puebloingles.com.
