This is idiotic advice. This is a fraction of any reputable SEO's hourly wage, and any proper on-page job would take hours including research. "The client should be crazy" to not want to pay for quality work that's only purpose is to bring him more sales, genius.ask abt 10$ .. the client should be crazy to give you more
thanks for all your help and info, my client and I decided to make it $40 per site, i think its a good price to start with.
cheers!
