There are all sorts of factors affecting the rates of coverage for both the binder and the aggregate used in surface dressing and it's a skill that really does require an experienced team with all the right equipment.
For most Surface Dressing teams, the season is now all but over - the end of September is widely accepted as the last date for acceptable conditions to ensure a fairly reasonable result. I'd be very inclined, given the weather outside right now, to leave such a project until next Spring.
With a single size 6mm aggregate (S6) and assuming a single spread technique, a professional team should achieve 90-120 m² per tonne, but that's based on effective sweping and re-use with minimal surplus cover.
