Everyone knows that Instagram is already dust. It still works for those who established themselves but for a new account it'll be a little tougher. Not saying it can't be done. I would start off by still hitting the 1500 likes per day. make sure you gear it towards your target audience. ie)nature photos, fashion, etc. Also, start following and unfollowing (whatever the limits may be). Then post quality content. Original content is always cool to see but its up to you. Good luck.
oh sorry no quick ways at the moment for organic followers. you can always buy 100k but whats the point.
