Hi @ameyn21,
I can't comment on all of your spaCy steps, but I think you don't have enough data for what you're trying to do.
If you're training a new entity type, I recommend checking out the flowchart that @ines put together. You can find it here: Annotation Flowchart: Named Entity Recognition
The first item on the flowchart says if you don't have > 1000 items, gather more data
