Shouldnt be too much, depending on your game progression i think it ranges from $200~500, which is negligible against the other contracts you may need to buy, going over 10k+. So long as you dont really f*ck up, you should be able to make that much in the same day with shop work, builder guild, mage guild, school work, flower sell, junk sell, TownHall contracts and the likes (many options unlock later on, but youll have enough ways to earn money is my point)
