First, for what it's worth - I started as a network guy and moved into SQL because I loved it (I liked Cisco). I even took a little pay cut at the time but have never regretted it.
I would say I am an high amateur SQL user currently. I can set up jobs, schedules, backups, replication, write basic queries and have had a hand in writing basic stored procedures.
Don't sell yourself short - I would consider that to be a higher than amateur. Especially if you understand Replication. The market for SQL talent is bonkers right now; I know companies that have had DBA/SQL Dev jobs open for over a year. If you are serious about making a move into the world of being a DBA I suggest that you come back to SQL Server Central (SSC) as often as you can. I have been doing SQL since 1999 and feel like I learned more in the past few years digesting as much info as possible. This site is a goldmine and the people who write articles here are some of the best in the business IMHO.
