Can a person only send large amounts an have a $500 transaction log between us before he could send? How can i get around this?
Sounds like a scam; that's not how Bitcoin works. I wouldn't have high expectations about the outcome of this. The goal is to get you to send them money.

I would say the following:

Send me the $500 and I'll partly refund you once your transaction is confirmed.

This is because, unlike bank transactions, transactions in Bitcoin are irreversible and it's not possible for them to &quot;transact and cancel the transactions&quot;.
