For candelabras, try Shinoda Design Center in Miramar. I love this store, they sell silk flowers and home decor for retail displays and the like. You need a business license to get an account there, but if you know someone with one, they can sign up and you can buy with their account. Also, I know some of the major party rental companies rent candelabras, but they'll be on the pricey side.
