Looking for Advice

I'm thinking about a second army, I'm definitely into Chaos but I'd like something "different" to mess around with on occasion. My main thing, I think I want a shooty army, probably an Orc army. I was wondering if anyone could give me some advice, I'm guessing maxing out the Lobbers and Chuckers, but what then?

Gobbos with bows and the poison banner. Doom Divers, and anything in general is good from the book.

You can definitely get shooty from o&g but reliable is another thing.

Spear Chukkas. Dirt cheap and you can take so many of them.

As for the Poison Banner, it is too expensive now. Has to be on a BSB too. Too many points to waste on a gobbo archer unit. Orc archers are nice too, as they can fight. And NG archers can have fanatics.
