Brickalying quantity - How many bricks per hour?

[dig dug dan]

I am pricing a landscaping job at the moment, and as I am not a bricklayer, I sub out any bricklaying.
The wall is 16.5m on a curve, will be 1.5m high, and will be freestanding, i.e. not a retaining wall, therefore, facing bricks both sides
According to my calculations, thats 2970 bricks.
Assuming the bricklayer has a mate to mix and hod, how long would this expect to take? how many bricks can he feasably lay in a day/hour?

I have estimated 5days. am i way off the mark here?

60 bricks to the square metre and most 1+1 brickies would expect to lay a minimum of 10 square metres of facing work per day.
