Multiple sites need SEO (PLEASE MUST READ THE ADVERT)

We are happy with our SEO but the provider doesn't have the capacity to take on our new sites. We are looking for quotes for up to 5 sites. You will not be paid anything until we see results!!!!!! Also, when I have advertised for SEO previously on odesk the quotes have been for stupid amounts of money. I know the value of SEO so don't give stupid quotes. So that I can make a judgement of your pricing I need the following quote for one of our current sites that is already SEO'ed: [login to view URL] This site is No:1 on google for the keywords "essay editing services" and "essay editing service" How much would you charge (monthly) to keep us at the same position? YOU MUST GIVE THIS INFORMATION WITH YOU QUOTE
