You can buy online people who will like your page. I don't know a website because I've never done it before. One place you could look into though if you want to spend some money is Fiverr. I'm sure that you would be able to find a gig on there where someone could get you likes. Also, the more promoting you do on social media the better. I find that it's so easy to get people to come to your page if you work for it. You could also do like for like with another page. That might also work because there are people who are always looking for more likes, just like you. And the last way that I can think of is if you join groups, you might find that people will like you page. I have heard some people have success with Facebook groups, and promoting in them.
