Honestly, personally I've only eaten pork steaks about 6 or 8 times in my life. They were delicious and I/we never had nor used any BBQ sauce... It's like asking; how much BBQ sauce on a beef steak, IMHO.
Probably want about 30 bottles of a mixture of different sauces, from A-1, Heinz 57, perhaps a few with BBQ sauce in 'em...

Lake Sinclair, GA (strategically about an hour from darn near anywhere)
Started competing in chili cookoffs back in the 1990's and have competed in more than I care to count. I became a CBJ in MiM in 2005, then MBN and in GBA in 2010. I've probably judged 130+- BBQ comps (sanctioned and unsanctioned) over this time. That said, I really enjoy competing more than I enjoy judging, and hope to get back to doing 4 or 5 a year in the near future.
