1) DBA work is usually, by definition, 24/7. It's just the nature of the beast. We're frequently on call to handle emergencies. That said, most of the time, it's a 9-5 job with occasional bouts of extreme excitement at 3AM.

2) Consulting usually requires travel unless you work for one of the businesses that supply DBA services remotely. I'm not saying not to look at or take consulting work, but it is different.

3) Tons and tons of people are still using 2008 and 2005. Way too many people are using 2000. So your skills are not really out of date at all. Not to mention that the fundamentals in SQL Server 2014 are not radically different from SQL Server 2005. You should be fine. But, if you're sweating your skills, find your local user group and start attending their meetings to bump your skills up. Find a local SQL Saturday event and spend the day getting learning on.

Best of luck in your search.
