Sharing experiences about do SEO for website

[daniel_do]

Hello everyone,
I am a Web Administrator for a Premium Fashion Brand of designer NGUYEN CONG TRI (Vietnam, Asia).
newbielink:http://congtri.net/ [nonactive] is the website that I have responsibility.

Beside building a website with quality pictures and contents, I also concentrate to do SEO for website.

After a month for doing SEO, today I check the result of my working. I got the details of it:  P.A = 10, D.A = 6, 47 Internal links (DoFollow), 7 external backlinks (3 DoFollow, 4 NoFollow).
and when I check my website at newbielink:http://majesticseo.com. [nonactive]
I got 15 Trust Flow links and 20 Citation Links, 8 External backlinks

My questions:

1. To become a quality website with higher ranking, what is the minimum P.A and D.A of the website? (they are have to: P.A = 50, D.A=50 or higher, aren't they? )
2. Normally, to do SEO for a website, if we will try to do it everyday, How long we can get a good results? (I heard someone said that" at least 6 months, It is correct, isn't it? )

I would like to receive any advices of you guys who have experiences about do SEO.
Thank you for your time and I look forward to your reply.

Regards,
Daniel
