REPAIR SHOP LAWSUIT HOW TO FIND A LAWYER IN ILLINOIS

I paid a repair shop to fix a coolant leak coming from between head and block. I brought it back to them 3 times and they still cannot fix it and refuse to refund the money I paid them claiming they took it apart 3 times and only charged me once so I should consider myself lucky. All Lawyers I contact do not handle these cases because of the knowledge needed to hold this shop accountable. This Happened in Illinois. Any help would be greatly appreciated... Between them taking my factory head off replacing it with there aftermarket head with the same results I am out a 10k dollar head and 7k in repairs along with 3 weeks of lost revenue
