Website Management Onpage-off-page-SEO

We have a network of over 650 city domains all relating to 1 specific construction service initially the sites were designed a spun with similar content as we only relied on payed traffic IE google ads etc now we are looking for a team to fully optimize all the sites with there own unique content so we can drive organic traffic to each individual city site this will require a strong team who are dedicated to making this network of sites rank over all our competitors in the long term.
