I have put some questions and information on a web page: http://www.billdietrich.me/MovingToSpain.html

I can't seem to find an agency (in New Jersey USA would be best) to help me through the application process.
I've contacted several, and they all say something like "we can't help you, consulate doesn't allow third-party representation".
I know I have to go in person to consulate a couple of times, I just want them to handle translations, coordination of documents,
finding a doctor, handling FBI check, etc. I've told them so. Still no go.

Maybe I'm looking for the wrong thing ? I searched online for "visa agency"; do I need an immigration lawyer, or some other category ?

Thanks.
