If you do an image search for "micro campers", "MPV Campers", "camper conversion" etc it will bring up allsorts to give you an idea of what you want and then you could find a local joiner to make it for you.
When I was researching mine I came accross a joiner advertising himself who made ones to your design for about £400-£500 which is a fraction of an Amdro, though that wouldn't include the cushions, blinds and stove etc but you can just use a Thermarest and you must aready have a stove (the non pressurised alcohol stoves with the Amdro must take forever to cook anyway). You can get some foil bubble wrap and suction cups off ebay to make the blinds yourself.
