How to choose link building service for new website .Please help!

Hi , I need help and suggestion from the established members about the choosing services for my website .
Some stats :
My site was created just two months ago
It is Weight loss , fitness niche , beauty niche ( big mistake )
About 1000-1200 unique visits per month (I know that it's not much , but it's my first project )
66 posts 500-900 words .
8$ with adsense monthly
bounce rate 54 % .
There are NO backlinks yet and I'm not sure which link building service I have to choose to increase my traffic and revenue . There are so many services on BHW , so I'm confused ...Should it be guest posts ,wheel or pyramid backlinks or any other backlinks strategy for a new website in 2015 ?
Or which BHW link building service do you suggest ( give me a link , please )?

Thanks

Also , I saw a lot of websites on flippa that had 100 visits monthly and making 5$ and next month 20.000 visits and making 600$ ... How is it possible ??

I like to start off by building some branding with legit looking social mention profiles. I only use as anchor text the name of the website or naked url. I also like to build a few comment backlinks (not spammy ones) using naked url or brand anchor text. From there you can get a bit more aggresive with PBN and tiered Web 2.0

Yes my question is also this which backlink service is good for new sites like mine

From your description it sounds like you have already started targeting keywords, building content and articles to suit. If I were in the same boots I would look at your lowest competition keywords / pages with highest search, then build links to those pages.
To get started I would register a Pinterest account, setup a few pin boards, pin various content and pin a few of yours in the mix.
Then ideally get start building some weebly and tumblr links:-

Setup a google plus account, then get some social shares for the main pages on your site. I use expressfans real social signals to appear that your website looks popular.
Then before looking at a pbn you are going to need link diversity, t0mmy's discusses it here:-

So to answer your question I use this service:-

Good luck!

Whatever links you get for your site make sure they don't get you penalized in the long run.
Avoid backlinks from footers/sidebars and site-wide links. Also make sure you don't get too specific and repeat your anchor text so often as to make it look spammy.

Thanks guys for your replies . I don't want to start link building by myself because I don't want to harm my site , that is why I'm looking for professional service. The main question is how many links can be created at the first month if there were no links before ? As I know if I create too many links it can harm , isn't it ? I have a facebook page with 20 real likes , Instagram with 1000 followers , twitter with 400 and pinterest( 5 boards) with 0 followers . Actually I don't understand how pinterest works at all . I'm using massplaner for Instagram and pinterest and pinterest is for me like a dark forest . Anyway when I 'm checking backlinks to my site it shows 0 .../

The answer to many you can build is: It depends on your site/niche/content on your site/your targeted keywords etc..

I would start out with a strong PR to give your website some good brand/naked link anchors while working on maybe blogger outreach for guest posts. I mainly just use guest posting for link building because of the authority and the referral traffic is nice too.

Weight loss, fitness and beauty are co-related niches but when it comes to seo, you need to target each separately.

Initially optimize your on page seo and try reduce the bounce rate percentage even more by adding videos, suggested posts etc. After that, try to find all in one backlinks service and use it for your homepage to boost the authority and then target different pages individually.
