You could always buy some HQ followers to help make your account/brand look more established and legitimate. I wouldn't go overboard since you're looking for real followers, but a few hundred/thousand might help establish your legitimacy.
I'd tell your actual friends to follow you, and have their friends follow you too. You could offer a small reward for sharing your pages and such as well, possibly credits/coupons that can be used later to actually buy your product.
There's always paying for advertising as well if you want to go down that route. I always thought buying a bunch of stickers/decals of your handle/brand and placing them everywhere you can couple help bring followers as well. Bathroom stalls, parking garages, light poles, etc. It's probably illegal, but eh, it's not permanent.
