AlwaysSAI...I'm sure if you request-some of these vendors would be more than happy to make items for your GLO...In fact, I think that all NATIONAL orgs. should have stuff made for them....It would be easy to start making Alpha Phi Omega, Gamma Sigma Sigma, Omega Phi Alpha, Sigma Alpha Iota, Phi Mu Alpha, etc. stuff...they need to also include the NPHC and multi-cutural GLOs, as well....Even if you are not National-I'm sure if you and some of your brothers/ sisters get together-you could request a bulk order....that would probably work....Good Luck!
