1 holder needed for a T3 submission

Where is the best place to get a minimum quantity of oversized card holders for a T3. I have a whopping 2 to submit and I only have 1 card protector. Any other ideas to submit a T3 that would be acceptable to PSA?

Any card with a declared value of $1,000 - $2,499 and all T3s must be submitted at this service level or higher. This includes autographed cards.>>
