Liking followers instagram service

How can I make that kind of service? I assume I need alot of instagram accounts, and some kind of manager. How can i do that?

Thank you!

insta promoter
insta booster
these are Instagram auto followers bot, but its not good to you, it will not give natural followers. so better you avoid this kind of bots, i just mentioned only these two but more number of bots are available in google. so try to get natural followers.
