PSA help?

[trib01]

This got accidentally posted on the BST...

As someone who collects premiums and supplements mainly, I like to have as many graded as I can. This is because as much as I am a collector at heart - I also have an investment. Grading is a great way to protect them for me.
There are several premium or supplements sets that were never cataloged. They are recognized by OldCardboard and various other hobby sites, but because they are not cataloged, PSA won't touch them. I have emailed a few times with PSA, but ultimately Net54, OldCardboard etc. just doesn't registered with PSA as "recognized" authorities to establish a checklist or credible info to grade them. Has anyone had any luck with something like this before? I have tried to supply PSA with all of the names I can think from this board that are actually mentioned in the Standard Catalog pages. Enough rambling - anyone have any insights or suggestions?
