Try Farm Relief Services, based near Kilmacthomas on main Waterford-Dungarvan road. I found them to be the cheapest for timber post and rail.
How many mesh panels do you need ? I have about 10-12 along with bases, which I will be finished with shortly on my site. You can buy them new from Morris's Providers or Brooks / Heitons etc.
I will need about 16 in total how soon are yours finished with i will need them in the next two weeks we could arrange a deal if you were done with yours. Ill try the farm relief this morning thank you.
