Mr.Dale howdy! You are so right on the money with the idea to market to the universities through the Ncaa and alumni organizations. There are millions of people who are either alumni or dedicated fans of their schools sports teams. Since there are so many universities that have huge numbers of followers the design for the urn could basically be the same with variations on the plaque attached and the color schemes. This approach to the manufacturing process would also apply to the armed forces types of urns while still separating the branches and paying proper tribute to each of them.
This type of process would lend itself very well to the manufacturing phase of the operation and keep operation costs down.
BTW: USC RULES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Notre Dame, not so much!!!!!!!!!!!!!!!!!!!!!!!!!
