What is pma?
I don't know what the acronym stands for. It's a premium account of some sort. I gotta keep $25k in it to avoid fees, and as it happens that's in the ballpark of the kind of money I'm comfortable having in the mainstream in these times of massive derivatives trading and the new popularity of 'bail-ins' as a means of solving financial crises.
I would mention to the OP, that I was thinking of a situation where actual cash (the green paper stuff) was deposited in my name. Not account-to-account transfers. That is how Bitcoin-Brokers does things. They act in part as an escrow agent for the transaction as well as a general organizer it seems. I was not (and am not) aware of any 'localbitcoins'-like method for doing anything other than face-to-face transactions because I've not looked at it for a while. There was some bug on their web site when I tried to set up an account, and I felt it unlikely to be effective for my needs anyway so I didn't bother to peruse the issue.
