I think I have read the same question somewhere in this forum. I went to SEO websites that provide SEO service. I took a look at their price list and compare each of their services/packages. I think it is fair to see it there than ask all the people to reveal their prices in an open forum. But that's just me. If you wanna know sample of pricing, you can PM me. However, price from SEO company or individual will be different, and it depends on your main aim too. Usually SEO company only offers bulk package, but SEO indvidual can do small packages. Both can do it good or bad.
