shahabraja,
did you ever sign a retainer agreement or any other professional services agreement with that lawyer ?
As a first step, ask for a minute by minute accounting of the hours he billed you for.
It sounds like a cheap shot of your old company trying to squeeze some money from you after you left them. (aehm wait a second, they fired you. Probably they stiffed the lawyer on his bill and he is trying to get from you what the company still owed him.)
otoh, he got your 485 through, 2k is not that unreasonable for that service alone. Maybe you would want to resolve this in a nonconfrontational way. I am not sure whether he has a valid claim against you if you never actually hired him. If he does have a valid claim, offer him a settlement for 1k.
As for the other idiots here: It clutters up the board tremendously if you keep responding to each others posts. I am supprised the administrator hasn't booted both of you yet.
