I have finally read this post and cant understand how this stuff seems to go so wrong. Owning a shop I can see both sides and sometimes you dont quote right but that becomes the shops problem unless it was worked out with the Client before hand. Things dont always go right and it sucks to see this stuff happen to anyone.
We try very hard to keep work around the quotes and sometimes that is very difficult because the way everything changes. But we do our best and we stand behind what we say and do.
I have no problem donating money to help something gone bad and would hope that anyone of you would do the same for all of us. Now that I have donated for the project when do I get to borrow it for the weekend. That was part of the deal right?
Good luck with finishing the project and hold your head up high because as you can see you have a lot of good guys backing you here. Please keep us updated on the progress and pictures.
