[macbethads1]

Hello how are you? I am about to start a project on a 2D game, I am going to base myself a lot on games like Megaman and Megaman Zero, I already have the story created, the plots, and also the game mode, but as I mentioned, the game will be in 2D and before to start it I want to know how much it will cost for the 2D animations, the characters, etc. Can someone help me calculate the cost of all this? If you know any company that can give me an estimate on the cost of all this much better
