Forgot to ask last time, I'm wondering what's the best way to tackle the sand bed. My current thinking is to have the 4 ton of sand delivered in jumbo bags and then spread, wack and screed managable areas of sand in sections.
I would then lay the blocks over this area before doing the same again on the next bit of sub base, rather than spread the whole 4 ton, wack it and then screed managable areas for laying.
My concern arises from the uncertainty over the weather in the next week or so, as I thought it would be better to protect the sand bed until I was ready to start laying the blocks.
I can't see any problem with your plan. If the sand is being delivered in Big Bags, then bear in mind that each 'tonne' only covers around 10m² or so and even working on your own, you should be able to pave over that area in less than a couple of hours.
