I don't offer either service in my secondary shop; #1, if I insert the picture & send it I've just invited the person to copy & paste & make their own. #2, my time is vluable $ #3 I used to do custom work & I've discovered it's a whole world of trouble out there! Some people do it & do it well, but it's nothing I'm willing to do. If you do go for it, put in a limit as to how many changes you will make before charging additional fees for processing. Also, considering that you're selling your cards for under $15 I wouldn;t offer pre-design services, at least without a retaining fee (have customers pay $5 for a 'look-see' at what the card would look like) so nobody gets the bright idea that they could easily get a free card from you.
