You should review federal attorneys in your district. You might go to the court and watch attorneys in action, you could review on PACER the court submissions of attorneys for cases pending in your district, you should interview several attorneys to get their understanding of the law as it would apply to your case, and you should have a clear understanding of what you can realistically afford. A very experienced federal attorney will probably cost more than you are allotting, but have an honest conversation with the attorney you chose about your finances and maybe you can come to an agreement.

The answer provided is meant to be instructional only.

On the basis of my own experience in federal court I would suggest that while a fee in the neighborhood of $10,000 might be reasonable in some drug conspiracy cases it would be hopelessly inadequate for most. I suggest that you find a list of attorneys who do good quality federal defense work in Tennessee and that when you discuss your case with several of them you go into the matter of what it would cost. The attorneys will expect this. But do not let cost be your primaty consideration. You need a good, conscientious attorney who will have, or can quickly earn, and maintain the respect of the court and the prosecutor and with whom you are able to work effectively. Good luck.
