- Have some business cards printed off before the wedding and carry them on the day
- Dry clean a suit before the wedding. The aim is to look smart and professional at all times - all of which will make an impression on guests and again, hopefully generate some business.
- Spend time looking at the work of good wedding photographers - a great source of inspiration. Get ideas about how to pose the couple and creative angles.
