I think without more details it is very hard to tell if hour building in Spain is a good idea.
It may be hard to believe but the cost of hour building in the UK is almost the same as in the USA when all the costs are factored in, I suspect that the same is true of Spain.
Only when you post the full details can people decide if this idea is an economic way of doing things or a holiday with a bit of flying attached.
