Need Expert WordPress PHP developer who can perform right now

WordPress plugin backend We need help with the underlying functionality of a Wordpress plugin we are creating for a client. The client runs thousands of auto service stations across the US and they want site visitors to be able to find locations by postal code. The list of locations changes often and the client wants to be able to just provide the contents of an Excel file (in CSV format). The designers have already built the user interface for the plugin so you'll be filling in the missing logic piece. Notes Each location in $franchises_string has one or more regions (identified by "region_codes") that they serve The $region_mappings_string provides the "postal_code" to "region_code" relationships Deliverables Complete the logic for FranchiseSearch You can structure your code however you like, as long as the class FranchiseSearch responds to these two methods: initialize($franchises_string, $region_mappings_string) search($postal_code) Results should be sorted alphabetically by franchise name
