Need quick paypal help!!

So paypal limited my account to verify recent transactions (selling gold)

They want just personal info and then like invoices from "suppliers" which I don't have because I bot a lot of gold. I mean. I buy mills too. But those aren't official suppliers. I haven't had any chargebacks on my account or anything so I know this is just a normal check. But what should I tell them about suppliers and what I sell?

Thanks guys for the help.
