Looking For A Custom Trellis Source

If you know of a place where I could get a trellis comparable to the one in the pics, please let me know. I have tried the home improvement stores, but they are very limited. The plant nurseries around me haven't been able to point me in the right direction either. I really only need them probably have the size as the ones in the pictures. I'm hoping someone here with commercial construction or landscaping might know a source. Thanks in advance.
