Deploy a flutter travel app on google play along with admin panel on firebase, bought from canyon.

Hello, I bought this app [login to view URL] from [login to view URL] I request you to please go on this link once and read the description of the application. They have provided with the complete kit for iOS and Android along with the Admin Panel. I want you to deploy this app on google play store for me along with the firebase admin panel. Along with that I need you to make short changes for me in this application. Like, I want to add custom made travel itineraries on the home page of the app. They have added a detailed guide on a pdf on how to deploy the admin panel and then the application. (If you are a flutter developer you already know it all but please once refer to that as well) Alright that's it. You can ask me anything else if you want to. I also need you to answer these few questions for me. I am not from this field of work. I might be a not so smart client to you but I will surely give you the best review if you can do this simple small work :)
