Hi Ricky,
Any number of companies offer lockable beds, aircon and furniture packages.
A couple of forum members have paid around 500 euro for a satellite package but I don't know who supplies it - a quick word with Sue at Centrepoint should help you there.
For furniture packages, I know of DBJ and Villapac but we used Furniture Express from Estepona - I would highly recommend them.
Hope this helps.
Cheers,
Don
