After reading your project needs, I can confidently say that I can complete your project well within the time I have stated. I have experience in making several Android apps (for myself as well for other clients). Many of my apps include an SQLite database with insert, delete and update operations. And similar to what is required by your app, in a recent app of mine, I had to fetch that data on a ListView (a custom ListView with a custom adapter).
So, basically, I already have enough experience doing what needs to be done in your app. Also, I know how to add "Backup/Restore" operations to SQLite database. So, I can add these operations to your app too, if you need so.
Since this would be my first freelancing job (if you so decide), I am asking for a very reasonable price for the job. And I am sure that once you have seen my work, you would definitely be willing to work with me in the future again. Thanks!
