Obtain usernames from inactive social media accounts

I need someone who is able to obtain a couple usernames from inactive users on the social media websites instagram and twitter. I don't need the users profile, I just need the username transferred to an account that I can use them on. The user profiles have each been inactive for 4+ years, don't have profile pictures and have 1 to no pics/updates on them. If you are able to help me obtain these usernames from these inactive accounts please place your bid.
