following my pm earlier I am happy to give this a go but don't have the rules or any figures - so if you can bring 2 forces then great - I suggest keeping it on the smaller side unless you know the rules well.
I will see if I can find my Orks but don't hold your breath they are buried somewhere in the loft!
cheers
Rob
Kind regards
