Doing mine at the moment..
if the ground is good you will probably need 6-7 loads of hard core (3 inch or down) to go 300mm deep then at 8euro a tonne (150 tonnes roughly)
Finishing with 804 at 9 euro a tonne will set you back 3 loads or 60 tonnes.
Finishing kerbing will be anywhere from 4.50 per metre to 7 euro per metre.
This is malerial only so work out labour hours for one to one and 1/2 weeks for 2 to 3 people with machinery,rollers and laying kerbing.
I cant give you a ball park on labour as im doing it myslef.
