I am having a hard time figuring out why you are doing all of this. It appears that you want only "approved" dealers to purchase from you.

Can you not just create a membership level and then in admin - general options "Enable sign-up for membership"? By making all of your products (and/or categories) a certain membership level they will not be visible except to "members" of that membership level once they have logged in.

You can have them directed to a page where they can download your "Application.pdf" and once they have completed your process you can approve their membership and place them accordingly.
