How does a MQ work?

[rohrmj]

Sorry if this is in the wrong forum ; )

I have just about 30k for my Shammy Epic MQ. But, I have never done a MQ with someone before and I am not sure what the etiquette is.

30k is a lot of plat (taken me months to get it), how does a MQ transaction go down?

Do you usually give half up front, then the rest when its done?

Is the transaction done at the bank ( can barley move with 10k on me)?

Thanks everyone!
