Increase my Google PR to 4 from 2 or make it under 1lac Alexa Rank

Hi, I need my Google PR from 2 to 4 or make my site rank within 1 Lac as per Alexa rank. In reply, please mention how are you going to achieve it with timeline. I did SEO myself before, so please don't come with spam bids. Waiting for some decent bids, please include "PR" on the top of bid so that I understand you have read the description. And also no agency contractor, here might be regular work for skilled SEO person as I'm freelancer also so have clients who want SEO for their sites. Thank you all!
