I need the assistance of an individual/team, who has experience configuring a website so that the phone number in the header, changes depending on the source, as indicated in the URL string. Example: A paid search campaign uses the URL appendage "/?ref=summerppc?ref=care to display the appropriately assigned phone number.
I have two sites that need help with this. Both are wordpress.
Please only apply if you have experience dealing with this sort of dynamic scripting.
