just submit your links on all marketing avenues and be patient cause it will really take time to achieve the desire PR
Agree with other comments it is really a waiting game, in the meantime keep costs at a minimum and try and do as much work yourself as possible. Make sure you keep adding content everyday, even if its garbage or spun content. This will keep the bots coming and eventually your rank will increase.
HI. The work which you have done of SEO is nice but you should post your one article minimum to 100 directories and atleast you have to make 10.000 links of it than you will see result after 60days. All links must be from DOFOLLOW.
it depends on Your Theme also. Would it be better choice to choose this. You must have got traffic from investment. And how much attractive are your blogposts, articles and website pages. May be your site structure is not good or you are targeting too much competiive keyphrases that why your ranking is not improving.
