Export list of users from an Instagram account

I want the followers of the account which have 'crossfit' in its name to be exported in a excel/csv file from the account [login to view URL] They have over 1.6 mil followers, and there should be around 100,000 - 500,000 accounts with 'crossfit' in their name. I WILL ONLY ACCEPT PEOPLE WHO SEND ME AN EXAMPLE OF 10 ACCOUNTS MATCHING THE REQUIREMENT ABOVE WITH 'CROSSFIT' IN THE NAME AND ARE A FOLLOWER OF THE ACCOUNT ABOVE.
