zuki,bear in mind i live in spain ,some friends of mine (a small band of 6 english musicians) wanted to open a store here so what they did was ,they went to the spanish schools with the intention of teaching kids to play different instruments ,and also be able to sell the instruments to the kids,a great idea but their premises was large and cheap but it was off the beaten track,so after about 6 months of trading they started going down hill because there was no easy transport for the kids to get to the lessons ,and so interest started to fall and now their business is in trouble,so make sure you cover ALL eventualities,i wish you luck,mike
