create my amazon seller account

Hello! I am in need of assistance setting up my Amazon seller account. I am looking to open a Professional Seller Account, and I already have some of the information and documents required, but need help with the remaining elements. I am unsure at this point if I will need assistance with managing my account post-setup but would like to discuss this further. I am looking for an experienced freelancer to help set up the account, so hopefully I can find someone to help me out. Thank you!
