Portion-controlled soymilk creamers for coffee

In the past, I have written about the market's need for a portion-control soymilk business, business producing soymilk as coffee creamers in small portions.

My reading is that somewhere, somehow, such products are on the market, but I'm unsure where that it.

When the dairies that make portion-controlled items produce those products, it's not done by dairies that produce soymilk exclusively (if at all).

We ought to ASK for this kind of product; then businesses would rise up to produce it.

Is there any reason that there ought NOT to be such enterprises, sponsored by private or venture capital?

For instance, if an entrepreneur wanted to create a portion-control soymilk business, s/he would research the portion-control milk business, see what equipment is used to make these products, scope out the suppliers of the equipment and supplies that are used, create 2 or more plans for developing the business (unique and nonunique) discern whether either plan is feasible (as a unique producer of portion-controlled soymilk coffee creamers AND as a contractor to portion-controlled creamers to produce soymilk 'runs' - no pun intended) for coffee marketers at various levels.
