the top side sounds expensive, ours was about 550 metres, 2 stiles, 5 gates, came out about 1,700 for the labour.
presumably the rammer is the tractor mounted type, hope the tractor driver knows how to use it, our contractor had learnt all sorts of clever little 'tricks' (use a piece of wood to gauge height so each post is the same). and they worked as a team so they each knew just what to do.
