advice rank 4 year old domain

i have not worked on this domain since 4 years
site exits

site had good alexa last year


but hardly any visitor this year

keywords I want to target
keyword1- exact local search volume 14800 - competition low
keyword2- exact local search volume 4400 - competition medium
keyword3- exact local search volume 880 - competition medium

keyword4- exact local search volume 94500 - competition high
keyword5- exact local search volume 25500 - competition high

keyword6- exact local search volume 36 - low

for keyword 5th I was on 2 nd page

I am using google external tool

i am below 50 in serps for all these keywords


In last three months I have done
article submission
UAW
bookmarking
angela
link pyramid
web2 links

I have been buying services on fiverr

I am about to buy scrape box and xrummer blast...

but before that i thought I should get your opinion

site is clean with unique and duplicate content
no copyright issues....
different pages target different keywords kept keyword density below 1%
its 1-2 times in 400+ word articles.

your opinion matters..

please advice and guide I have not yet mastered seo...

So what is competition high, medium & low for you? Those words mean different things to different people.

wellcompetition high medium and low is indicated by google external keyword tool

keyword2- exact local search volume 4400 - competition medium

google webmaster tool shows me on first page
and google search does not shows me at all in first 10 pages ( not in top 100)

its a wordpress blog
