Amazon Beauty Brand Setup Help

I already have an active Amazon Seller Central account (USA marketplace).

I have a private label teeth whitening product under my own brand (MISÁ).

I have completed part of the setup process, including:
• Seller account verification
• Initial GTIN exemption request
• Draft product listing started

However, I need an experienced Amazon expert to review everything, correct errors, and fully complete the setup properly so I can start selling.
What I Need Help With:
1. Re-submit and properly secure GTIN Exemption under my correct brand name
2. Review brand name consistency across account
3. Create and optimize a new product listing (Beauty category)
4. Ensure compliance for teeth whitening products (Amazon policy check)
5. Help with category approval if required
6. Set up FBA shipment correctly
7. Confirm UPC/GTIN exemption is correctly applied to listing
8. Check that my account health and compliance are clean
9. Final review before product goes live
