LLC REGISTRATION USA AMAZON

I am looking to register a single-member LLC in the US on the Amazon platform. I need help with the registration process as well as getting a bank account set up for the LLC. I am open to hearing any suggestions you may have to ensure successful setup of the LLC. Please respond if you are confident in your ability to facilitate the registration of a US-based LLC on Amazon plus provide assistance with setting up a bank account for the LLC. Thank you.
