Don't forget to do some link building of your own - on your own site. Wedding photographers have a great content ready to go; not to mention a willing audience of bloggers/websites to post it. Find some recent pictures and submit them to the wedding blogs. Have your client do an 'engagement shot' for new couple. Those photos will make it up on the couple's wedding websites - ask for a link back. Do some PR around your local media to get on the 'Best of' lists.
