Now I'm starting to get annoyed

I recently bought a beautiful Ted Williams 1941 Play Ball card PSA 7 oc for a great price and it comes no problems.
I post it on ebay $850 obo and a man emails me with a phone number and says he is interested in the card, I call the number. The guy seemed pretty nice and offered $700 money order and he will send it out asap. After a week I get no MO from him so I email him asking if it was sent yet and he responds in 2 days "yes" that was literally the entire email. After another week I still have no MO so I email him asking for a tracking number but nothing so I proceed to tell him I am canceling our arrangement and he never replies.
I relist the card on ebay.
After a couple days I receive an offer for $700 from PaperTreasure I accept the offer and receive an email from him thanking me for accepting his offer and asking me to send an invoice. Finally! Communication from a buyer! I then send him and invoice and its been two days and nothing so I go to send him an email and I see "not a registered user" I am getting pretty sick of these "buyers" and after looking at his recent purchases I have a feeling that I am not the only person who will be missing out money.

BTW: I am fully aware of the fact that I am an idiot for accepting an offer from a 2 feedback buyer... and an idiot for not having immediate payment on BINs
My question: How can I expedite getting my FVFs back? I know there is a waiting period for filing a NPB.
Also: I still have the Williams card for sale I am bringing it to the National today and I am also going Friday
