Need a Korean Phone Number to Create Bunjang/Joonggonara Accounts

Hello! I live in the US and would like to browse Bunjang and Joonggonara with the intent of getting a proxy service to help me buy the goods. I would like for you to either: A) Sell me a Korean phone number that I would be able to receive text verification codes from the US B) Sell me Bunjang and/or Joonggonara Account(s) - if you are willing to provide me with a proxy service and deliver to the US, please do contact me about that as well! Thank you so much!
