Psst. $30 an hour equals over $62,000 per year. Which if you explore the current pay rate for graphics designers is above average. That is at 200 X 15. But you charge $30 so the end user is paying a $120K plus salary. Now the only graphics designers paid that kind of money don't bother with this type of stuff. So as you describe it you are creating an object. Charging for you time and effort. Then after arriving at that figure marking up the product 100%. I have to ask what loan shark is nailing you for 50%. Who or what ever that is, give them the slip. I never heard of any type of legitimate distribution arragement the has you doing the work but gets 50% of the gross. Get an agent, you only have to pay them 10% Credit card processing gets another 10% Shipping, well it's a download so there is no shipping. Heck add another 5% miscellanious costs and you end up with 25% insted of 50. Now you can drop the end price 25% and still retain the same income. But maybe from this new price you will sell more units and actually make more money.
