Remote learning support

I’m running a small business and trying to boost my presence on Instagram. I’ve heard that buying followers can help, but I’m hesitant because I don’t want to risk having fake accounts following me. I want to make sure the service I use is reliable and provides real followers. I also want to ensure that the followers I get will engage with my content, not just inflate my numbers. What services have you guys used that you felt were safe and effective?
