Which direction do I put my desk and my clients chairs in a real estate offfice that is 10×12 to use feng shui

all I know about feng shui is to not face a door, and also not have your back to a door. The one with natural light would be better

Placement:
1. Face your desk so that you can see people entering the room. Do not put it directly across from the door.
2. Any chairs placed in the room should not be in front of or across from the door, should face your desk, and should be able to see a door. Do not put them into a corner either — you shouldn't be sitting in one either (you can angle yourself to the corner, but put something else in it). Lining up along a wall is fine, but don't crowd close to it.
3. If the angled corner is an open corner (as in, it is a corner that faces outward and you can place things in the angle), then place a plant/shelves/table in it diagonally. If it is a closed corner (points into the room), you need to soften it by placing a plant or a large/tall, rounded object — as far to the edge on one side of the corner as you can or at the corner, effectively rounding it off. If the layout/space doesn't allow for that, you can also hang a tapestry/decorative cloth on the most open-to-the-office side of the corner so that it just barely overlaps the corner, thereby softening it.
4. If you choose the office across from the workroom, place a medium sized fountain next to the doorway (on a table or something) closest to it — it will block out some of the ambient noise and help "convert" the bad electronic vibes into wealth ones. If that spot is N, SE, or SW, all the better.
5. Do not place seating areas/desk closer than 5 feet from the main doorway (when the door is closed) — it blocks chi flow and will stop people from entering the room.
6. If you get the office with the afternoon light, do not place anything where it hits except a fountain — without seeing the situation, a mirror, seating area, plant, etc could all be bad, so putting nothing there or a fountain is the best option.
7. Keep the trash can out of view from the door.
8. Try to leave an open area in front of the door. If there is a second door directly across from it, then put an "anchor" between them — a table, a plant, a large pot, an armchair, etc.

Decorating:
1. If you have fluorescent lighting, get at least one incandescent lamp for your office, especially if you have no windows. It is best if your clients can benefit from it too, so a floor lamp and a desk lamp would be best.
2. Use natural elements to decorate your office, especially wood and metal — earth and metal elements being the most auspicious combination for prosperity. Stone is also acceptable. White is a metallic color, so if you have that for walls, use wooden, gray, or dark furniture.
3. If you have a lot of office clutter that occurs on a daily basis, get some closed storage boxes (not plastic or clear) to contain the daily clutter. Do not keep stuff that "you might need later"; if you really can't throw it out yet for that reason, get a filing cabinet or a box specifically for that stuff. Once it gets full, don't get another one, but take something old out for each thing you put in that's new.
4. Get rid of any furniture that does not serve a purpose. Excess, low-purposed stuff is your enemy. Decorative objects should be carefully selected and moved around, but do not add to them without taking something away.
5. Get some landscape pictures. This is important if you have no windows. Vacation destinations (without business logos, so they focus on wanting be there) would be best for you.
6. A couple of plants (nothing spiny or pointy) are good, but, if you're not good with plants, don't bring them in your office to die. Dying and dead things are bad. So are fake plants. Stick with wooden sculpture, fountains, candles and other decorative objects, but keep them in balance with each other.
7. For objects meant for drawing interest or adding to the feel of a room, arrange them in odd-numbered sets, with each object at a different height/depth if possible. If you have several of these in a single area, try to make sure they are different numbers. For objects not meant to draw much attention, but just help fill the room or to be at hand, arrange them in even numbered sets, with objects all at similar heights/depths, and as symmetrically as possible.
