Thanks. Who said anything about lack of specification? That is to be agreed prior to signing any contract however before you get into detailed specification you obviously need to get a ballpark figure to decide if you want to go ahead ? No point working up a detailed specification only to find it is 40k and way over budget - then everyone's time is wasted. We've discussed approximate spec but not detailed, that's next stage. I just didn't want to be ripped off, but in a way although this company hasn't done exactly this before I think that could be a plus point as they are wanting to go in this direction and will want something to show off.
What does evil diesel do ? Please don't say something incredibly similar to what you do !
