Personally I would hire a 1.5 tonne mini digger (probably 100 - 200 ish
for the week) and dig out the area to approx 30cm deep (how deep you
would go would depend a bit on the type of soil you have and how much
other "stuff" there is in it (tree roots etc).
Dump the spoil in a couple of large skips (approx 130 each). Backfill
approx 20cm with type 1 MOT road stone (probably under 15/tonne if you
get it delivered in the "empty" skips - again if the ground is unstable
/ soft you may want to dig deeper and have some hard core under the Type
1) then level it off and tamp it down with a plate vibrator.
Next about 5cm of sharp sand - level and vibrate. Lay the blocks, and
vibrate them flat (with a rubber protecting mat on the plate vibrator).
Finally sweep in a dry soft sand and cement mix to grout the blocks.
No idea what it would cost to "have done" - but it is sure to be several K.
Also consider patterned concrete. I have it and it's totally brilliant.
Cost... around £50/sqm up to £90sqm if you get ripped off by a sales
I paid £58sqm as did many of my neighbours and we're all very pleased with
the result and after three years it still looks like new - unlike sets which
always seem to inherit the odd dip no matter how good the sub base.
What is patterned concrete? I have never heard of it. Do you have a
website where I can see how it looks.
We would rather get the driveway "done", than to diy, since the hubby
is not that great with big projects - that said I have to get some
guys to redo the fencing in the garden - at present it is leaning like
the Pisa tower.
