Not in my city. They ask for a lot more than webbing. Plus if anything is wrong or not done exactly to spec, they refuse the order and won't pay. It seems most sign shops in the city won't do it, they now have to source to out of the area shops. I've spoken with several sign shops that won't do it.
I don't understand the issue.
Your client tells you what they want. You either can or cannot do it (impossible or you don't have the right equipment)
If you can do it, you quote it accordingly. If they agree to your given price, You make their item as they had originally asked, to their specs.
Now if you've done something wrong because it's not to their specs, it's your fault for not following the specs they've given you.
???????
sounds like they want a specific banner, and other people make it the way they feel like making it which is obviously wrong.
