Fastest Instagram Growth?

Hey BHW,

I've been building up two Instagram accounts this past month, one photography page and one men's fashion page. So far I've only been using followliker and instagress. My daily growth is around 40 – 70 followers with 1/6 engagement for the photography page and 20 – 30 followers and 1/3 engagement for the fashion page.

What are other methods can I use to maximize my growth? With a reasonable budget. I'm not trying to spend 1000 dollars on shout outs all across the board.
