looking for kaldi and ML expert for training

Now I developing Urudu SST(speech to text) project and I am using Kaldi ASPIRE recipe. And I have 250hours corpus. To making a model, I followed Kaldi manual steps but TDNN training was not converged. I can't find the reason. I think it can resolve by only a real-expert with Kaldi and speech-recognition skills. This task is very urgent one for me. If you are a real-expert and can help me in time, I will pay fully. Please don't hesitate to bid if you are a good kaldi and ML expert. Thanks.
