not sure, if you got much of a reply here, as this might be wrong audience here, but I would suggest using this site
playerup.comthey specialize in selling all types of accounts, including twitter. I know this, because back in April or so I sold my twitter account related to ICO research there. I had 2k followers at that point and sold it for $250, they even have an escrow service that they call Middleman. I think you will be better off there and you can charge in crypto too.
good luck selling your account
