I Need A Good Lawyer

I have worked for this company in Nigeria over 15years now. The company had some problem between the three directors over money issues which made it difficult for them to pay the workers and with that they drop some of the workers including me without the last three years pay, compensation and benefits. This has been on for about four years now, they always say they don't have money but they always travel abroad for vacations, parties e.t.c. I am old now and can't get a new job and I am badly in need of my money which the company has refused to pay for about four years. I need a good lawyer that can help me get my money but I don't have any money for a good lawyer. What should I do? Please help.
