Help for gauntlet mission B21

Hey ! I am looking for very good players who know well B21 to do the gauntlet mission on this map (doint the High Value Contract and Extracting with 4 million). In exchange I can help for Radiated Treasure or the 10 million Mission, or give NFCs. I am Legendary, and a very good player on Serpent Island, I have already completed all gauntlet missions by myself, except this one. Thanks !
