Thank you all for the replies!
Bowens was a serious contender, but the less expensive kits/lights don't have fan controlled systems, and due to the heavy short workload, I don't want to risk it.
Our budget btw, sry should have mentioned this earlier, is around 1000 euros, so about 1200 dollars.
But I still don't really know if a 400w/s with 200w/s set would be enough for full body shots. I can't find a good source on the net with good info about the watt/how much space it can light-ratio.
