Unity3D Work - Shooter Game Modifications -

I'm looking for someone to edit and add new features to my game. Currently it's a first person mobile shooter and everything works correctly but I need to add : - Ad adjustments / bugfix - A gun model/texture swapping screen. - Right now we can swap characters, but I have a new character build in parts tha we should be able to swap in the character creator ( swap character parts and texture used ) - Add a coin shop - Make sure character works ingame and gun are in the hands. The project seems to be pretty organized but the original coder is not available so the coder I want to hire should be experienced enough to look around and do the changes I need. I have a lot of unitypackages bought from the asset store from various packages that will increase workflow and make things easier and the AD / Purchase system should be done with Unity's payment system. More work will follow if all work is done well! Type 'GUNGAME' in the first part of your proposal so I know you read all this
