A lot of feng shui is common sense. You can get a book on feng shui and just do some basic work in your house to get the same effect as a 10K renovation.

I just helped a girlfriend redo her kitchen, using feng shui as a basis. The kitchen was dark, deep, and hardly had any countertop (all along one windowless side wall.) There was an enormous dining table up against the far wall (also windowless), which was painted white. We got the table and chairs out of the kitchen, put up shelving and a baker's rack with countertop for that far wall, hung shiny bottomed pans along the bakers rack and wall (reflective surface for the windows opposite), and got an island for the middle of the floor. Now her energy flows much better, I'm told. It was just a practical change - and it changed the way she and her cat actually use and move about in that room.

Think about how you use your space MORE than what the mystery of feng shui is. Do you face a wall when you eat or work? Put a mirror there, above your head, reflecting the area behind you. When you walk into your bedroom, where is your bed? When you lay in bed, can you see out the bedroom door? Wind chimes are useful for the metal part, and also let you know when you have a breeze. If your house is dark, put holiday lights on a tree or bunched in a corner. Place stones in corners or for paperweights. Think "elemental."
