New build house, going to use a main contractor. I've got full BR drawings and will get Bill of Quantities from online shop. But I'm still unclear about some vital things like windows: do we a) get quotes from window suppliers ourselves or b) specify in detail the specs for the windows and get the main contractor to get quotes and include that in his quote? Any advice would be very welcome. Do we specify all the internal finishes and joinery for one single quote or do shell and then interiors as 2 separate stages?

I'm trying to find an M&E consultant to do all the plans for: electrics, lighting, pipework, service runs etc, etc. I've got an architect who's done the plans to get us through planning permission but they now need these details added which he says we need an M&E consultant for. After a LOT of Googling it seems like most M&E consultants don't do residential, they're all in for big commercial projects. Can anyone recommend anyone for a single family house or recommend a better way to search than I've used up till now? Also any idea what a fair price is for this service? Many thanks in advance.
