A (too late?) suggestion to look at Heroics and Ros. While not in the same detail league as GHQ* they are more than 'good enough' when on the tabletop and the price is a third of GHQ - plus you can get as few as you need, not being committed to 5-packs.
*While I join in the praise of GHQ's quality (they are, after all, the local boys, and I did a short stint at the crucible back in the day...) there is -for myself, at least- the consideration of the extra time on the bench one will be tempted (if not required) to spend painting such beautiful minis!

If they're just a smallish piece of a project, 'good enough' may be the (cheaper - in both time and money) route to take?
