[Unique situation] How to build a FB audience from COMPLETE scratch ?

Hi fellow warriors !

I have a very a-typical scenario with a major problem showing up since beginning of my efforts.

I'm trying to build a Facebook fan page, more like a community page. Unfortunately even though I'm posting valuable content and interact with other users, groups and pages I keep struggling with gaining true exposure. Simply these efforts do not bring me any people who would hit that 'Like' button.

Why this situation is atypical ? Because none of the advices on internet or from WSO's that I've purchased seem to work. It seems that nobody takes into account a situation that one can not have any experience with social media before nor a situation in which someone can have no initial friends to share page to. It's like someone telling me 'why u no familliar with Social Media?! U mad bro ?'. But this is truth. I didn't yet find any blog post, WSO or youtube that would explain to me what to do in case if you begin TRULLY from a complete ZERO on a COMPLETELY NEW GROUND.

For instance I was never interested in Facebook, Twitter etc. I thought that it's a time waste to be there and didn't understand the people who shared nearly everything from their private life. I preferred to go bicycling at that time.

Due to the complicated circumstances of my current life situation I don't have contact with my older friends and not really a possibility to grow a list of new friends in my current situation. Even if it would be possible they would be from a completely different target market.

So in the end I can't invite anyone from my email list to like my facebook page, I can't set a tunnel from my other social media accounts to siphon followers or any fans to a new facebook page, I can't run Facebook ads due to very limited budget that I have now.

You get the basic idea. I have no one to share this page to because I have no contact with anyone. No followers, friends, email list, old businesses, budget for ads, family etc.

What I've tried and didn't work :

1. Find a target market and interact with them on different pages sharing same niche.

2. Post frequently at specified scheduled hours.

3. Post various things and not focus only on photos for example.

4. Tag faces of other users on FB that I saw liked my competition's pages

5. Use hashtags, comment other pages content, like content.

6. Like other pages and people.

7. Ask questions, add links, videos, write stories etc.

Most of the advices state a word 'grow' but no one ever explains how to 'seed'. You can't grow if you have just bald ground with no seed inside.

Can anyone help me with this a little bit ?

Thanks !

EDIT :

Situation have changed. I've decided to try facebook ads but unfortunately have huge difficulties with having them working and reaching anyone. Please refer to post number 10 for more infor. Thanks for any possible help !
