I need to find manufacturers of powdered drink mix (similar to
"Crystal Light") who contract pack private label brands.  The
manufacturer should be able to provide flavors such as lemonade,
lemon/lime, and fruit flavors.  The product must be sugar-free and
preferably sweetened with Splenda.  The manufacturers may be located
anywhere in the US, but Texas would be preferred. I have already found
Sturm Foods, but need to find additional manufacturers.
