Hey mate,
I would like to work on your iPhone App.
You mentioned the database is accessible on a desktop, so what kind of database do you have on your desktop? Also, is your iPhone App going to be connecting to the database via the internet or locally within your own network? I can definitely create the App shown in your App Requirement document, the scrollable section will be a table view with custom cells to display item and the item price, and then you will have 3 buttons for the categories and a label to describe the item.
You will also see on my freelancer profile, that I have only excellent reviews for the work done on here, and I intend to keep that reputation intact by continuing to do excellent work for my clients.
I can definitely create your app, so please feel free to start a conversation via chat to further discuss.
Kind Regards,
Canon
