+1 for LMI - There is also Hanover Brazil
http://www.hanoverbrazil.com/ Where CITES certified Rosewood is available but it is expensive and a lot of it appears somewhat slabby -
Bob Rigaud, my employers has quite an inventory of side and back sets, fingerboard blanks, bridge blanks, etc. available in BRW, Fiddleback Mahogany, Claro Walnut that he will sell - Again, they are not inexpensive, but as an earlier poster pointed out, scrimping on materials can be a false economy when hundreds of hours of labor are at stake.
Here is an example of a Braillian fingerboard blank
