Which would say sounds like a better name?
-General Partner
-Global Partner
-Top Partner
-Main Partner
-Exclusive Partner
Since you're already using metals for naming your packages: Bronze, Silver, Gold, Platinum...it only makes sense to add a Titanium package.
The names you are suggesting are good, but you'll need to change your naming convention to something like: Basic Partner, Standard Partner, Collaborative Partner, Exclusive Partner... Keep all naming conventions the same.
I hope this helps.
Two choices. Stick with metal and go to whatever is the next most precious :) or if this is a one co. only spot, I've done:
Partner and Title. Both sound more exclusive (IMO) to just another metal, LOL.
Platinum Plus.......you want to keep it in the same vein, thanks...Ken Queen
