Hi Katie! I do believe I can help you find the partner(s) you're looking for. But bear with me. :-)
1) I found the best way to meet other players is to attend a class or drill session. The Tennisplex offers several opportunities for after work players as well as Saturday sessions. I attend a Tuesday morning (9:30am) class so if you happen to have off , do a drop in. Kentlands, Quince Orchard, Cabin John...they all have classes you can sign up for.
2) Attend a tennis social, the local USTA has one every few months. Search on Montgomery County Tennis Association and signup for their newsletter.
3) Post a message online in Tennisopolis or Craigslist, though, to be honest, I've had very little luck this way.
4) I can try to set something up with some ladies but I'm not sure who's looking and who's available when.
I'll send a friend request with my email so we can try to get you some players.
