The way the business worked was that I was working full time in an unrelated s/w development job. My wife would pack the orders in the morning and the courier would pick up from our home location every afternoon. I looked after the invoicing etc. at night; but with an automated process it really didn't take up much extra time. I did try drop-shipping as well but it didn't work out as well for us, although of course drop-shipping would probably enable you to have a larger sales capacity.
