Learning business/professional Spanish for work in Spain

Hello! We have been dreaming of moving to Spain for a few years now, and we may be closer to such a reality due to my husband's ability to transfer for work. The actual move, if it happens, would still be at least a year away. There are lots of questions I have about being the spouse that doesn't have the job lined up when moving abroad, but right now, my main concern is preparation and positioning myself to be a marketable professional in Spain. I currently work at a major US bank, and my ideal would be to first try and do a lateral move to the same industry in Spain. I understand there are many challenges in being able to find work abroad, visa sponsorship, etc., but right now, I just want to up my language skills. Can anyone recommend a course of action in my situation? Any language/job advice specific to the expat looking for job in Spain is welcome. Thank you!
