that's a fierce distribution. Ha ha.
I'll give you a design fee reference. I'm from Shenzhen.
2 posters (width 61cm' height 81cm )=1111
4 exhibition stands (155mm'x61cm) =1111
one circular-arc spray painting (width 9m' height 2.6m) =2111
31 flags (width 71cm height 41cm) = 61. Height 76mm) =311
A3 11111 sheets on a single page (desktop A3 paper size) =811
4 triangular plates (length 25cm and width 12cm')=1511
4 pieces (diameter 61cm circle) =511
1 * * 7711 RMB. Plus 811RMB, now the supervision fee (this site definitely needs designers to go to the venue to coordinate)
