I also know of a freelancer who can add 6,000 to 8,000 followers to your account in a month for only $300.00. Non-spam, no porn, and no bots. No suspension as well. They can even manage your DMs and occasional tweets for a little additional fee if needed. I guess there's a growing amount of freelancers catering to online marketers needs.
I think you should have a free function for user get follower. It will help your service have traffic and users before sell package .
