Where to buy outdoor storage container for bikes

Hello there - we have a small apartment in Caleta de Velez and we are bringing out a couple of fold up bikes in April so that we can use them when we visit. Could anyone advise us where we might buy an outdoor storage container to put on our balcony so that we can keep the bikes locked up and stored permanently. We will be hiring a car when we visit so we could drive somewhere to collect it and we wondered if there might be somewhere in Torre del Mar or Velez Malaga to purchase the item. In an ideal world we would like to order something to be delivered when we are there but we have limited Spanish so this could be problematic.

We would really appreciate any advice. Thank you.

Best regards.
