Build a Website and blog around SEO. SEO p

I want to rebuild my website. I want a website built to be on the first page of google under 4 keywords. The keywords are mangosteen, mangosteen juice, xango, xango juice. This is my domain - www.mangosteenforsale.com. I want to transform this website into a informational website on mangosteen juice that will bring quality traffic to XanGo banner ads to xango stores. I don't want to sell product from the website, Just sell banner space to xango websites that sell xango. To sell the banner space I have to be on page one of google under the right keywords. That is why I want the website built for SEO first. Next I want it to look like a reliable/credible place to get information on mangosteen. Last I want it visually pleasing to keep and convert customers for our ads. I want a SEO friendly blog I can update every couple days. The goal is to drive massive quality mangosteen and xango targeted traffic to many websites. That is the only goal. The website/blog needs to have a easy to use admin panel. It can be wordpress, blogger, PHP, ect... I don't care. I want it to look good, be easy to update and change and on the front page of google on those 4 keywords... That's it..... I will escrow $200 to pay when the website/blog is done, SEO is started and we are able to place ads. I will escrow the remaining balance to pay when the google placement results are accomplished. I will ONLY pay SEO based on results. I will place the remaining funds in a escrow. When we get the agreed upon results You will get the funds. I'll give you up to 4 months. Please detail what your bid includes. Examples of your work and what you plan on building to get on the front page of those keywords.
