Need help creating some moo promo cards

I would like help in designing some promo cards (postcard format) for my photography business that I could use to communicate offers, leave in shops etc . Possibly two sets for two types of work I do (weddings and kids portraits). They would use my photography and would need to be consistent with my branding elements (logo, colours, feel,fonts).
