I can sell real world items for in game currency in this mobile market place app

While I was playing some mobile games I started getting really annoyed that items cost so much so I thought of an app where you can buy real world items in exchange for in game currency and market place apps already existed so I searched and searched but I think I came up empty but here it is,<br><br>Here is the idea in detail,<br><br> market place app with a twist is an app which connects both the marketplace and the mobile game , first the app would have all games listed and then you connect your Google play store to the app and they would look into the games you play and show you the items that are for sale in your games, then you just buy the item and it gets sent to your Google play account so you can use it in the game then you just ship the real world item to the person you bought it from and when they confirm receiving it then the in game items get transferred to your account, and if someone tried to take something without shipping it then they would get banned from the app and if a item wasn’t sent to someone then they would get a refund for in game currency<br><br>I can’t code but I think it’s doable because the app would have full access to your Google play account so it has all information to get the items,<br><br>Here is a list of things the app would need<br><br>1) market place app with lists of things people are selling , with name/seller name/how much it costs etc<br>2) items would sell for in game currency (gold coins etc)<br>3) list of mobile games available to connect to market place<br>4) access to Google play account<br>5) confirmation of shipping/receiving item<br>6) confirmation of receiving in game item<br>7) list of banned people to prevent scams<br>8) list of in game items market place can buy/sell<br>9) access to in game currency so market place app can buy/sell in game items<br><br>This might have existed but I don’t know of any app like this, I couldn’t code this and I don’t have time to make it so please consider making this
