Franchisor Corporate Website on WIX

Our service business is now a franchise and we are seeking help to make the site usable for the franchisor to control location pages in other states and cities. We would like the contact info for each location to populate due to the searchers' location. We also want to maintain our domain authority as much as possible. We want organic SEO to still work for each location.

Another thing is I want each location to have its on services pages to rand better in certain categories.
