Automating follow/unfollow on Twitter is against it's ToS and I wouldn't​ recommend it even if it wasn't. Use Crowdfire instead. It helps you find people with similar interests on Twitter and offers some great options to organically grow your audience. You will have to spend about 15 minutes a day on it but it's time well spent.
