if your income from this activity is significant, a personal opinion, you may want to discuss with a tax professional the advantages and disadvantages of converting to an S-Corporation. With an S-Corp some of the profits come out as a salary to you from which both you and the S-Corp will pay social security and medicare taxes. the remaining profit would not be subject to these taxes. There are many pros and cons to an S-Corp which need to be discussed with a pro who can look over your entire tax situation for proper advice. This is beyond the scope of this forum.
