There are some of us who represent tenants. But you need a consultation because there are some important questions to answer. For instance, what kind of notice did you give when you left? What justification does the landlord have for such a delay? Can you pay a lawyer an amount equal perhaps to 1/2 or 2/3 of what you're seeking on the understanding that, if you win, you will get your fees back? Is it better to go to small claims without a lawyer? The best result may be to settle with the landlord, and having a lawyer would help with that.
You would need an attorney that does landlord/tenant work and is familiar with litigating these claims. There are a number of issues raised by the other answer that are valid and would need to be addressed to determine what results you might be able to obtain. Good luck.
