I see that no different than the taxes that are taken out of your check when you work for someone else. But you still need to figure in profit ON TOP of wages for a BUSINESS to make money - not necessarily you but the business, but essentially you are one and the same. (this was in your link - Self-employment tax (SE tax) is a social security and Medicare tax primarily for individuals who work for themselves. It is similar to the social security and Medicare taxes withheld from the pay of most wage earners.) BTW, WHY would you NOT want to get more for your mounts if you can? Suppose you are charging $350 and they give you a $200 tip, would you take it or refuse it ???
