I need a quick price for a boundary wall at the front of the house.
The builders are in doing a major extension and the brickies have
offered to build a wall at the front of the house along the pavement.

There's already a single course wall there, they'll just have to knock
that layer off. So there's no foundations or anything to dig. It will
be 27 feet long and 5 courses high (6 courses if funds allow). We also
want a small pillar at each end, just 7 or 8 courses high.

How much should this cost, in (a) engineering brick and (b) pinhole
brick.

Thanks.
