You might have to set the readerQuotas for the binding as shown below:

            WSHttpBinding binding1 = new WSHttpBinding();
            binding1.MaxBufferPoolSize = 2147483647;
            binding1.MaxReceivedMessageSize = 2147483647;            

            var myReaderQuotas1 = new XmlDictionaryReaderQuotas();
            myReaderQuotas1.MaxStringContentLength = 2147483647;
            myReaderQuotas1.MaxDepth = 2147483647;
            myReaderQuotas1.MaxArrayLength = 2147483647;
            myReaderQuotas1.MaxBytesPerRead = 2147483647;
            myReaderQuotas1.MaxNameTableCharCount = 2147483647;
            binding1.GetType().GetProperty("ReaderQuotas").SetValue(binding1, myReaderQuotas1, null);

The reason is that setting quotas on a binding that has already been created has no effect.

Also you would need to consider increasing your "MaxItemsInObjectGraph" value of the DataContractSerializer on both client and server to a large value.

Change the following setting in web.config

 <configuration> 
    <system.web> 
        <httpRuntime maxRequestLength="xxxx" /> 
    </system.web> 
</configuration> 

xxxx is the value in KB you want to set it to.
