If you can come to this site and start a thread, I'm pretty sure you can do everything on your own. The forms are very simple and straightforward. You won't be saved of time even with lawyer because he'll ask all the info from you to be filled in some questionnaire or their own form which you could directly do on EE profile. It'd personally give you more sense of satisfaction. If at all you are stuck with any question, you can always post here or dig in to this site.
Plenty of people with consultant repent at later stages knowing how simple the process was, and also not being able to know what really exists in their profile. They also get worried by lack of updates too. If you own d everything, you could see what's happening every single day to your profile. It's up to you. You could just try creating a ee profile and see how it works for you. That could help you come to a decision if you'd really need someone to manage your profile.
