I've malted my own barley, wheat and corn several times. It's a relatively simple thing to do and makes good beer.
There's several tricks of the trade which you'll get better at in no time. Knowing how much and how long to steep, when to stop malting and start kilning, how high a temperature to kiln, etc...
In fact, I'm drinking my last batch of home malted beer now. It's excellent.
You won't save time or money, but it's a neat experience and makes you realize why you're paying $1.50/lb or $30 - $50 a sack for malted barley.
You can take it to extremes with temperature control, water makeup, etc...
You say you're going to use your "farm" and grow barley, great! Make sure you get a malting variety.
The BYO article referenced earlier provides some good advice.
Good luck.
