I have created an essay site that has over 200,000 essays, book reports, and exams on various topics. The site is coded in PHP and includes PayPal Web Payments Pro integration and a great backend that combines PHP/MYSQL and Sphinx. We add a few thousand essays every day.
I have paid for design, SEO, and coded the backend myself. There is an automated sitemap system that has been submitted to Yahoo and Google.
What I am looking for is someone to build links and to be an SEO officer and give SEO advice. I'm offering 5-10% of the profits that come from my site depending on your resume, something which we can negotiate.
Contact me and I will answer any questions you have and share additional details.
