Class Rings for schools outside US

I have been asked to develop a class ring program for Universities
and High Schools in a small country near the US. We will probably
like to have them made through one of the US Mfg. The distribution
can be handled locally through a local jewelry store partner and
local sales associate recruitment.

We are looking for the right Mfg partner- an existing class ring
house that can provide the support- visual selling aids like
brochures and low volume custom rings (The first targeted school has
255 graduating students in September in 5 educational areas) in a
variety of metals and price points.

Any suggestions on who is great to work with? Range of start-up
costs? What visual aids work well (we are unlikely to find school
papers or media to advertise in). Any idea on what % of students buy
class rings?
