Texas contract law, subcontractor's right to collect money owed by general contractor

You may be able to file a mechanic's lien on the property you did the work on, but it sounds like this was probably multiple pptys. Suing in small claims court may be the best bet. You'd need to do so in the county where the company is located. Unfortunately, the small claims limit in KS is only $4000. See link below for KS small claims info. You can also try LegalZoom, a company that can file small claims for you.
