Ky intermodal?

I'm new to the site and just looking for some information and any help is appreciated. I have my own authority and have been pulling lumber and logs for while now. I'm looking at mabe getting set up to pull containers into the rail yard and emptys back to the customer. I'm having a hard time finding out how to get the work of pulling the containers. I kno one customer said he can request for me to pull his containers but I'm not sure. Thanks in advance
