Hello again. I am 99% sure this scammer was here a few days ago (wallet recovery service).
This is a SCAM, for many reasons, one of them - you're paying for nothing, there is not way the website knows what you're paying for - just the BTC amount you want to give them
<form name="input" action="buy.php" method="post"><input type="hidden" name="amount" value="5.56114919"><input type="submit" value="Buy Wallet"></form>
Also, even if (s)he sends you the wallet, and it was encrypted - he could withdraw the BTC instantly if (s)he had the private key.
