Well maybe 1 Dev is enough if he can manage to make the demo, I don't know if a strategy game can fit 100 events that is why I stated Construct Classic for the demo if the dev want to continue in Construct Classic that will also be fine.
There will be no NDA until crowd funding is done, since we will be just talking on what to put in the demo and since all the mechanics and plans will be publish in public NDA is not necessary at this point.
Offers will be finalized after I have the team since the team number is not yet definite.
Rev-Sharing will start after the game is finished and starts to make money, the money generated from Crowd Funding will be split into software purchases, wages for other devs/artists and other misc fees. The Dev/s that will be hired here will also receive some compensation with the Crowd Funding funds depending on how much we raise in the campaign.
