Short Sale (real Estate) - Sueing Realtor For 10% Of Contract

As the title says me and my realtor are suing the selling realtor for 10% of the contract price because he failed to do anything in a timely manner, blamed us for not being able to get a mortgage loan finished in 2 weeks, forged an email from his counterpart at the bank, failed to follow contract stipulations, and then allowed the sale to fall through due to his own negligence.

The contract stated within 72 hrs he needed to get the sale info to my mortgage lender and turn on gas and water. It took him a full month to do both. Our contract ended on the 11th on the 10th we sent him a request for extension and he stated that he does not want to extend because we failed to do anything in a timely manner. After you got the info to my mortgage lender she turned it around to me in 24 hours I signed it. Then as soon as he turned on gas and water we finished the inspection that day we only had a week for the inspection but he failed to turn it on so we couldn't finish it until he turned it on. He then sent us an email from somebody at the bank that my realtor had previously corresponded with saying that we need to whine less and work more with a whole bunch of misspells and typos he also took off her email, phone # and fax # from her signature block.

I was just wondering if anybody has ever had to do this and what it all entails legally? My realtor thinks it's a sure thing I don't know what it will even entail.

If I've left any info out just ask not sure what is and is not important. We are located in Louisiana.
