Google Ranking for top 10 Keywords

I want to rank my website on top 10 position on Google for 17 keywords. I would want the result to last for atleast 1 months time. I strongly believe in white hat methods; so if you are advocates of black hats kindly do not bid on this project. I would pay you once I see the ranking report in the Google web master. I have more than 100 keywords to be optimized so the projects would be recurring only that I would like to see the results for the 17 keywords and then we can talk about the long term assignments. Kindly also let me know the time you would require for this optimization. Thanks for your bidding. Thanks, Utpal
