I had the same problem. I got in touch with Aifos of all people, and a bloke called gregor on number 0034678485496 was very helpfull, He emailed me over the copy of the boletin for the electric and also a copy of the 1st occupational licence, you will also need your passport number and your Spanish bank details. Then call this number 0034 902 509 509.
Thanks
Garry
