Some US Immigration firms that specialize in EB-5, like ours, have worked with different sources of EB-5 investors. What we can also offer is a review of the documentation you have already provided to get it in a position of EB-5 compliance and marketability to these sources and their investors. Calling a law firm like ours should be one of your first steps.
We would suggest that you retain an experienced immigration attorney who may be able to refer you to an intermediary who has access to investors for a small EB-5 raise such as yours.
