Auto lister for Selling App Mercari

I need you to develop some software for me. I would like this software to be developed for Windows . I am looking to pay to have an autolister created for the mobile selling app Mercari. I will need the app to function on Android os without root or for the Windows 10 PC No macro program. The program/app should be able to auto list items with correct photos, a description, condition, select the appropriate category, shipping preference, location (Postal code), and pricing. It sounds fairly simple - I have some previous coding experience, but cannot seem to get this correct, so I am looking for someone else. I'd like to stay around the 30$-70$ mark if possible. I am starting out selling on Mercari and hope to boost some listings/sales.
