Starting one up could be a great idea. Very often taking a product / service that is popular in one county / culture and setting it up in another makes a great business opportunity.
Where are you going to be in Spain?
How much have you looked into it?
Perhaps this is big city stuff where you could start small, do lots of local advertising, prove your usefullness and grow.
I'd be interested to see how you get on and what you decide to do as I am interested in entrepreneurship. I am also interested in how the culture of entrepreneurship differs between in latin cultures and anglo saxon cultures. I am an "anglo saxon" entrpreneur in Spain.
Sorry for going off topic a bit.
Let me know if you want to engage.
Good luck.
