Yes, you can sue them.
You'll need approximately $10,000 to pay an attorney's retainer. That's just to get the case started.
You'll need to find a lawyer that will take your case. Most honest lawyers won't do it. If you tell the prospective candidates right up front that you've got $10K to spend, you'll eventually find an unscrupulous attorney who will take your money.
Expect the case to take several years to wind it's way through the legal process before going to trial. By that time, your initial $10K will have been spent, so you'll need to come up with many thousands of dollars more.
All with absolutely NO guarantee that you'll win anything.
Good luck.
