round here id say
panels about £30 each (actually £26.50)
boards £10
posts £12-15
so i reckon £400 of materials
and I’d get my mate do do it, prob a days work for 2 blokes (mates rates) £200
so i’d be paying £600,, plus bit more for cement/ballast etc
2 blokes should get that done in a day – unless they have to remove old stuff first
