16 metres of wall framing - I'd budget about 1 to 2 man days to frame out if I were really going at it, with a labourer to help raise the frames into place. That's assuming that you are using 3.2 metre timbers to make the framing, and it's being made up on the floor as something like 6 separate frames on the floor and raised into position, then fixed. If you can't cut and assemble in situ or you have to make it up vertically it will take longer. Door openings also add to the time as they can be relatively labour intensive. To board out I'd budget 1-1/2 days to board out (single side) simply because you are up and down ladders with the top cuts.
The foregoing is assuming I have an SDS (to fix the sole plate down, assuming concrete), chop saw, cordless circ saw and a framing nailer. Boarding would be done using a collated driver. All assuming no oddities in wall shapes, floor and ceiling not diverging too much, materials stacked ready to go, not having to fix the header into steel, etc. Based on having done two double-sided infills between two shop units last year which were a bit bigger than yours (14 no x 2.4 metre frames x 4 metres high)
As FMT says, it isn't easy to quote without actually seeing the job in person
As to daily rates, they vary a heck of a lot. We are currently in the "happy time" when all the schools and colleges get work done, there is a shortage of skilled trades, and even the agencies are offering £25/hour and above for day work. Independents generally charge more than that, with rates in my area now being £250 to £300/day, I'm told
