Also, is PayPal a standard method of payment? I don't yet have an ample supply of Bitcoin and want to hold as much as I can for the rebound.
No, but for that, you just need to talk with your chosen escrows and see if you can arrange a deal with them using Paypal as a medium transaction.
But I've never seen an escrow here accepting a deal like that. Seems it requires extra work.
But no harm trying. Just choose the reputable ones.
