Create an Advanced SEO Plugin for Wordpress

Hi, We would like to hire a professional which is capable to Build a SEO Plugin for Worpress similar to S.E.O--PRESSOR. The plugin should have the same or even more features as the one we want to copy. It should have a totally different design and code structure!!! ... we don't want to violate any Copyright laws. I will respond only to PROFESSIONAL developers, i need a quality job to be done. Best Regards!
