Amazon FBA LLC Setup and Brand Registry

I’m looking for an experienced professional to provide a complete Amazon FBA business setup for a Pakistani seller. The package should include US LLC formation, EIN and required LLC documentation, Amazon Seller Central account setup, support with Amazon verification and approval, Amazon Brand Registry setup, and trademark guidance if needed for Brand Registry. I need someone with proven experience helping non-US residents launch Amazon FBA accounts and can handle the process professionally and compliantly. Please share your relevant experience, what is included in your package, total cost including government and trademark fees, estimated timeline, and any additional documents or information you will need from me.
