its POSSIBLE but i DO NOT suggest it. if you get it wrong the cts will throw the book at you. it will end up being more expensive in the long run and you will have no recourse for things like deadline mistakes, what should be filed where, and who should be notified and by when. you could get your self in a LOT of financial trouble that will take a while to get out of, if you do. i'm just saying consider what you are paying for. they are professionals for a reason.
