I can recommend Naturediet, it is excellent quality in every respect.
One thing I would just say - you are doing your little pup no favours by changing his food all the time. You are actually reinforcing his picky eating habits. I would strongly recommend that you pick a good quality food and stick to it. If he doesn't eat it within 15 or 20 minutes, pick up the bowl until the next mealtime.
It is absolutely fine to have kibble for breakfast and wet food at teatime, and it can be very convenient to have a dog who is happy to eat either type of food.
