Agree with you. I started looking for "pure" contractor but every Tom Dick & Harry calls themselves an ID nowadays, even those "uncle" types from the boondocks. But surprisingly when I called for quotes from "pure" contractors and IDs the cost is very very similar, so I went with someone who was able to understand my needs (plus speak decent English cos my CL2 is half past six and my Hokkien even worse). So I think we have to face it, in this day and age, just use an ID. Benefit is that they will help you co-ordinate and you only have one person you need to shout or scold rather than screaming and chasing 10 different sub-contractors...
