Think to gain indirectly from Instagram : If you are proficient at something, think of making some free videos for promotion and then participate at online platformes (Skillshare, lynda...) => give paid courses that you promote for your fellowers / or sell directly your services from your account...
Also, you can be a bridge for advertissement (like the compaign signature in this forum)... the other ways are said before from members...
Good luck for you !!!
