Fortunately, a number of services like Namechk and KnowEm exist so that you can check to see what services have your desired username available. Today, KnowEm is launching some new services to make searching and registering usernames that much easier, across social sites.
The basic KnowEm search service is free. You can search more than 330 social media networks for your desired username to see what's out there and what has already been snatched up. If you don't have an established brand name, this can also be an opportunity to evaluate the right name to use.
Now, in addition to letting you search sites and get links to sign-up for free, KnowEm is offering three different packages to make signing up for accounts even easier.
The Corporate Edition clocks in at $350, but will register your desired username across 150 of the top social websites, set-up your profile, avatar, bio/description and URL. This is all done by KnowEm staffers in New Jersey and they set things up so you don't have to worry.
The Individual Edition is $99 and will start the sign-up process at 150 different social sites. You'll still need to confirm the sign-ups and populate the accounts with your own information.
For the true social media addict, KnowEm also offers a subscription service for $49 a month that will automatically register your username on 30 new social networks a month.
Although I think that many individuals and businesses underestimate the importance of having a solidified online identity, I'm not sure how many businesses will be prepared to have the sign-up process done for them.
