Ha...... based upon your post. You have an employee dedicated to doing 25 a day. Otherwise, it's just another empty statement. Try basing your comments on things you know or things you are experienced in doing. Not some fabricated wannabe throwing out dumb numbers.
The numbers I used are merely based upon facts. If you're gonna go to the trouble of vectorizing a piece of artwork, as by your own earlier statements can take up to an hour or as little as 10 minutes, the average cost of that job is probably worth around $1,200 to $1,500 each. Even if it's as little as $1,000, that's still $125,000 a week, according to your statistics.
Therefore, if you're not making decent money on your various projects, then you're giving work away you can't really afford. Thus, your doing art for free is just plain dumb.
However, do as you feel is best for your business to keep your doors open. It was only about a year ago you were advertising for help and moving into a brick building, so I guess you don't need to charge for your stuff, huh ??
