I am a lawyer in Israel. Recently, the Spanish government announced that it would give Spanish citizenship to Jews that are originally from Spain
See for example
The regulation is not in force yet.
I have a website on this matter
I have clients who claim to be of Sephardi origins who are interested in obtaining Spanish citizenship. For them to be able to apply, they need Genealogy report that proves their Sephardi origins.
I need a freelancer with experience in the matter. It is preferable if freelancer know Hebrew. Freelancer is requested to provide work an CV that proves his expertise in the subject matter.
