Looking for a Lawyer for a breach of contract case

I am looking for a lawyer who knows how to handle a breach of contract case and will accept a contingent fee in an agreed percentage.
In the contract there is written the penalty amount in case of breach of contract.
I apologize that cannot post to much info and details.
Details will be given after I find the right lawyer and as you see I added the NDA option as it is very important to keep the details confidential.

edit:
Please let me know if the NDA is actually is hindering to send me a bid. thank you

Thank you
