I am sorry Flavio, but I am not a programmer, I do some web design stuff with a little HTML and CSS, nothing that gets complicated. I think it is more close to the shopping cart area, because if a person or a family wants to spend a weekend in a rural area away from the crowded cities they will need to pay the stay, a range between 35 to 70 euros for a day or two, so a shopping cart with that functionality would be ideal I guess.
Thanks for your time in responding and the tutorial.
Best regards,
