How Do I Do Full Advanced SEO Configuration for A WordPress Site

BHW is the best forum I have ever been to. And I believe that SEO experts here will help me to shed very bright light to this issue:

I have been talking to a lot of SEO gurus for SEO full configuration for a Wordpress site but I cannot afford their bills.

Please, I will like if gurus here give us the FULL packages for On-page and Off-Page SEO configurations for a WP site.

Thank you in anticipation. God bless BHW!
