Interior design for a new house

We have recently bought a new house and would like some help on the interior design front. The house has 4 double bedrooms and a large living/dining area. In addition to this there is a small study room and a L shaped kitchen.

There is also a garden at the back and we are planning to build a conservatory there.

We are looking for a full "online shopping list" consisting of furniture, furnishings, wallpaper etc.

Thanks
