What material are you using? If you're using wood $2000 for a walk-in closet is likely fair market price, you need to consider that they are supplying the material, designing, manufacturing (in the case where it is custom sizes, and shelves, etc), and installing... Else, Canadian Tire, and Home Depot have the sets where you install rails on the walls and can put in shelves, bars, drawers, etc.. (like in a retail store). but be cautious since these can quickly escalate in cost once you start adding in multiple shelves and drawers. for example: http://www.canadiantire.ca/AST/browse/3/HouseHome/StorageOrganization/ClosetOrganization/PRD~0681482P/Rubbermaid%252BConfigurations%252B4-8%252Bft.%252BKit/CROSSSELL~0681484%20Rubbermaid%2BConfigurations%2BSliding%2BWire%2BBasket.jsp?locale=en is the basic set up...one basket drawer would add 64.99$ to it... Unfortunately, like you, I,ve been looking for the best value in this topic, and haven't had any luck finding something inexpensive and good quality.

Here's another option: Ikea has some very nice, high quality, modern-looking products, and they also have a little-known installation service, so you can have them do all the work for you.
