Also any good tips for online printing (canvases, postcards, etc..)? Initially I was going to just provide print ready products but have had way too many requests for printing to not offer it.
You'll make more money printing yourself and selling wall art...as to just selling images digitally.
Watch the folks on CreativeLive.com....they have some really good folks on there talking how to make serious $$$ in the photography/videography business. Even if you don't shoot weddings, the wedding shooters on CL have great business ideas...and there are other specialty types there talking too (children, portrait...etc).
But again, everything they say is,,,,have them look at the images AT your studio, in person....and you might look into putting together packages to see of wall art/albums.....make those what they buy, price them so that ala-carte pricing is way more $$....
