Increase PR genuinely

I have an Indian directory site with PR of 3 (it was Pr 4 earlier). It has over 7-8000 unique visitors every month. However, I want the PR of the site to go to atleast 6 or 7. Therefore, please bid if you are confident. Once I choose the winning bidder, I will deposit the money in Escrow. Money will be released only after required PR is achieved. Mention the PR you can achieve in the bid. The bid should be based on minimum PR6. You can mention what is expected if higher PR is achieved. If you need any details from me, please use PMB. Let us not waste each other's time as in my last project, the winning bidder wasted more than a month and did not do any work.
