Right now I have twenty generic boyz with handweapons to do, plus the standard 4-piece command group - eventually this is going to be a unit of twenty including standard and musician, plus a hero-champion, leaving three figures spare.
Once these guys are done my next batch will be twenty arrer boyz (archers), then after that the goblins (20 melee, 20 archers), and after all of that who knows. I'm planning on painting the arrer boyz up as two units of ten, plus a hero-champion for each and the usual standard and musician for each.
I'm basically starting off with the minimums as per Warhammer Armies, though along the way I have also been bidding on various orcy-gobliny things on ebay as well. I'd love to be able to add in a unit of the old Regiments of Renown Mother Crushers and a unit of the Despoiling Hobgoblins as a mercenary detachment (the first unit I ever bought and fielded was the Despoiling Hobs), though that all depends on how well I can do ebay and various trades.
