I would be concerned at lifting each block weighing 20kg up 1.5m+

lbs - are you that much of a body builder that you can lift half a ton
of concrete 5 feet up in 4 hours. Then add in the mortar and the
mixing of it.

Its not that stressful. A plank on some spare blocks is all you need to
do the top.


If the customer is calling the shots then make him pay. This is a
full day's work plus materials.

That I agree with.

Treble the cost at least and look to
getting some assistance.


Depends on how much you want to make.
