Hello, I have a couple of questions relating to trademarks. A friend of mine is trying to get a service mark registered; the questions are as follows:

1)In choosing a class, my friend has encountered several services that fall under the umbrella of his organization (note: these services are all in the same class). Does he have to pay ~$300 for each service he chooses, or does the onetime payment cover as many service as he wishes to designate as long as they fall in the same class?
2)My friend's firm is an LLC, but he's considering converting to a corporation. if he registers his service mark now (i.e., as an LLC), will converting to a corporation in any way affect his registered service mark (assuming it gets issued by the USPTO)?

Please feel free to send me a message, as I rarely use tribe these days. Any help you can provide would be kindly appreciated.

Thanks!
Ali
