Ours was £230 but all hand stitched with ties and fire retardant. They were busy as flip pre World Cup (for obvious reasons) but I'm looking forward to seeing the finished product. If the fire certificate is part of the flag construction (just seen your earlier post) that's very handy. Charlie...
Got ours treated by Barmy Flags in Oldham as part of stitching a design onto an 18x9 flag I already owned.
You get a certificate with it proving it's been treated. Company said its standard practice now.
Design attached. Should be ready in couple weeks.
