Development of interior design of the store

We need an interior designer. It is necessary to develop the interior design of the hookah store. So we have a room of about 40 squares. We want to make a hookah shop there. We have a sense of taste, we are all right (that is, we can distinguish shit from shit), but we do not know how to do it ourselves. And therefore, you need the help of a person who will make a consultation (tell you what to do with the walls, floors, how to arrange furniture and rack, how to make light and so on) and tell you how to make the interior as budgetary as possible, but at the same time effectively (dust in the eyes) to make us an interior, and you will also need to write builders how to be. It is desirable if the person will be from MSK, so that he can give contacts from whom he could order / buy. Write immediately where you are from, that at an approximate price (I understand that this is not understandable shit, but nevertheless) and on time.
