How come there are hardly no attorneys that deal with tenant landlord laws?

I have a small claims case and I am seeking advice for my case I processed against my former roommate. She is disputing the claim and I was wanting legal advice regarding her letter she sent me regarding the summons she received from me.
She failed to pay rent and utilities when we had agreed to pay half of rent and utilities. She was forced to be removed off the lease voluntarily in order to avoid eviction from Landlord and I was granted to stay in property because I was paying rent and she was not. She claims to have been current on all rent and bills when she left property and lease agreement. That is incorrect, this is why she had to leave. I have all documentation to prove the matter here.
Her letter she sent to me also states she wants my proof of copies of my documentation to prove my claim because she was without any merit when she left she claims. However, I do not want to give her my documentation because it has all my personal information on it. I just told her the court will strictly handle the case and decide the judgment. Was that okay?
Any one know of attorneys who handle these kinds of cases in Cumberland, MD? Or is there a landlord tenant hot line to call?
She also claims in the letter if I had contacted her before filing suit, the matter could have been resolved quickly. This is wrong information from her, this is why I had filed the suit against her because she cut off all communication when she moved out after not paying her half of rent and utilities. This is the first time I have heard from her or get any response from her since August 2009 when it occurred.
Thanks Ranger! She’s just trying to blow a smoke screen and really digging herself a hole. She did not pay rent at all during her stay on the lease.
She will have rights to be shown the documentation at the court date to prove my claim. She had copies of everything when she left. She’s claiming now she does not have anything or got anything. I will send it to her certified mail and she signs it upon delivery each time, then she will say she never got it. . So, now I am not wanting to keep wasting anymore $$ on that.
