My clients are important to me and so I run a loyalty referral scheme. If I book a standard price full day wedding as a result of a referral from one of my wedding couples, both parties will be in line for goodies.
The couple that have referred me will receive a voucher for a free portrait shoot with the edited pictures by on-line download. The new couple will receive a free large print from their wedding.
So, if you recommend me to anyone, make sure to tell them to let me know that you've recommended me, to ensure that you both get your goodies.
