Looking for doubles (Beginner - Intermediate) Not sure

My girlfriend and I are looking for 2 players we can play doubles with?  Not really sure what rating I am.  She played varsity tennis doubles in high school.  I've been playing for 6 months.  I can kind of serve? my ground strokes are decent but my 1hand back hands are weak.  I'd say I'm a little better than her though.  I like to play at sand pointe after work on weekdays (singles...since my girlfriend goes to school in riverside) or we can play weekends at el camino or sand pointe (doubles..she will be in town).  Let me know!
