Making a spare room into a closet?

Ok here is what to do. You can cover the walls with white paneling, tack nailed down so for easy removal later on. Then go to a local resale shop. A lot of these places have cheap lighting there. One time I remodeled a small room with mirror on the walls, not only made the room optically bigger but a lot brighter! Walmart has this hanger that holes in them. You hang your clothes in the holes then you can open them up which makes them fold down giving you a lot more room in the closet. Really inexpensive. Menards also carries them or Lowes, or Home Depot. I would suggest 4 standing mirrors in each corner then a light in the middle of the room from above. Good Luck.
