Unpaid rent and attorney's fees, how to collect?

[Gina Nicolas]

Hello everyone, I have to evict one my tenants that left with 3500 dollars from unpaid rents with an additional of 2000 dollars in attorney fees.  She did not pay rent for 6 months and my PM did not do anything. I Fired the PM and hired a lawyer and evicted her but the damage was already done leaving me with thousands of dollars - unpaid rent. Now my question is, how can collect that money, should I hired a collection agency company or what other means out there to collect money she owes, also I don't want this to influence other tenants make them think that they can get away not paying rents but at the same time I don't want to spend one more dime trying to collect from her and not getting anything.
