offline SEO newbie need advice and proposal for outsourcing

Hi!

I'm completely new at off-site SEO so please understand my lack of understanding 'common sense - obvious' things.

I'm going to start few new web-pages (some as current businesses segments and one complete new businesses ) , so I have to find best off-site seo strategy (and a outsource partner for that) at the beginning, so I don't make same mistake again like with main domain and find about obvious steps after year of two struggling to reach best SERP's.


I've been trying to rank my page with on-site seo, made lot of mistakes, but also learned a lot along the way. I have many things to repair and to make but I've learned the basics and more.

After building some content I've realized that's really hard to reach top 10 positions on some completive keywords (keyphrases) , while some competitors (specifically one )
are easily showing there, even on keywords that they are not event trying to reach - all that with less content on the site - content valuable for specific scope of keywords.

I knew that he has quality backlins and that his domain rank is greater than mine.

Then I've subscribed to ahrefs trial and took a look at his backlinks.

One part of them were expected - valuable do-follow organics from high ranked blogs, influencers etc. The guy was very popular through one period and he made good connections with some blogs. had some premium subscriptions as vendor etc.

Second part with very high DR are youtube, vimeo etc. I was wondering why he has indexed backlinks from vimeo while I don't - Than I've realized that he probably has 2nd tier links, and I don't.

Third part of backlinks is various directories with high DR (~60) . Like viesearch etc. After doing some reserch, I've understand that he's been very active, or he has payed someone to do the job. anyway, not big sience, common sense that I wasn't doing. I've tried
to apply for some, than I've realized that I need to outsource that because for newbie like like it takes too much time and research.

Fourth part of links took most of my attention.

They are highly targeted mock web 2.0 blogposts with hight DR( ~60) like amoblog com, total-blog com, tribunalblog com etc etc etc. in last 2 weeks his backlinks rised from ~2K to >5K!

Those mock blogpost are obviously ones that should't be read by anyone, with just one link to his website, but yet they are quality content regarding his businesses topic. At first I thought that he is the author because the guy is very talented in writing, but
then I've realized that same author has 5 or more blogposts with various themes (automotive, football etc).

So that part is obviously outsourced.


I've read somewhere on this forum that if you play carefully with right dosage of blogposts like that, do 2nd tiers etc etc, then it's good strategy that's very safe in terms of eventual penalization.

Now, finally my question(s):


where can i find offers for such services with some references. Someone who will write and post on valuable blogs like those mentioned. Is this strategy a good strategy? Is this 'too good' content? Would less reader friendly content (cheaper) gain same results for backlinks?

one example of such blogposts: dantefhdy851blog.total-blog DOT com


does this comes in some kind of packages that includes applying to high ranked directories, building 2nd tiers for exising backlink etc. ?

Please, don't hestiate to give me good directions. Those KW that I'm after have 5-30 difficulty in ahref, competition is not so good like this guy, but they are 3-4 y. old sites with blog, not more than 20 posts per year..


Thank you!
