2d gaming app developer wanted

I have a 2d gaming app that I would like to have made. The name of this app is “Pogo Stick Rick”. It is about a kid whose name is Richard, but everyone calls him Rick and he wakes up to a world full of zombies, monsters, and aliens. The goal of this 2d game is to clear out all of the zombies in the games, but there are several different species and sub-species of zombies. As Rick ventures through this world, he will have the option to carry a limited amount of materials on him for upgrading his pogo stick, changing clothes, gloves, shoes, health packs, stamina packs, and electronic scrap for building a radio to try and contact the outside world. The player will have the choice to save survivors or leave them for the zombie menace (which will give the player a choice to make ally’s or play solo, but be careful, because some ally’s can double cross you). They name of the town is HiChester and it is a town that is connected to a mountain by a man made bridge. The town itself is fourteen miles long North to south and 7 miles wide west to east. This will be a long-term project and that means that I will need for whoever is chosen for this project, to eventually add in DLC’s, for example monsters and aliens as the player progresses through the game to keep the player coming back for more. There will be mission for the player to complete that will bring them to their ultimate goal, which at first is to find their family, but when they do and they find out that their family has been taken, their new goal is to wipe out the zombie menace. I have so much material for this gaming app and I know it will be the next biggest gaming app for iOS and android stores. If you have any questions, comments, or concerns, please message me and I will reply to you as soon as I can.
