I am in process of building a high grade PSA player set (admittedly post-war but could apply to pre-war). This player was a minor star so his cards are affordable but there aren't many graded. I have made good progress in the past 2 1/2 years since I started the set but now am having trouble finding high grade specimens even though I know there are a lot of ungraded examples out there.

I am wondering if anyone knows of companies/individuals that specialize and/or have had success in finding and submitting cards to PSA based on clients' want lists, perhaps companies/individuals with large inventories of cards?

Thanks,
Eric
