STK Right way to place a sell order?

[RobertHoff@xxxxxxx]

Greetings!

Yes, I'm a bit of a newbie when it comes to the correct / best way to place a
sell order.  Would you please give me your advice about how to place this
hypothetical order:

Time 10:00AM EST
XYZ  10 1/8  @ 3/8  20x10  Average daily volume 50,000  Today's H 10 1/4  L 9
5/8
Want to sell by market close 30,000 shares with ABC on-line broker charging
$10.00 up to 5,000 shares.

Thanks and happy trading,

Bob Hoff
