If you want to be valued, which is to say, if you want couples to pay that big fancy price you charge, you need to value yourself, value your clients, and value the work you do for them.
A practical example of that is highlighted by Luke today:
Wedding celebrants / officiants: the pen your couple signs their wedding paperwork with should cost more than $1.50
Personally, I like and use both the Mark One and Marker Plus, but you might be more of the Ti Arto EDC kind of folk. Either way, be valuable, bring value, show value, and they will value you.
