PUT BUSINESS SUPPLIERS ON A SECOND SITE - PUT LINKS TO BUSINESSES ON THAT SITE BUT ASLO COPY LINK TO MENU ITEMS ON MAIN SITE POITING TO THOSE BUSINESS CATEGORIES
This way businesses can register sperately and cannot interferee with marriage users.
ALSO PUT PARENTS THERE TOO - PLUS THE THEY CAN COMMUNICATE AND CHAT AND MAKE VIDEO CALLS TO EACH OTHER
ALSO PUT MEETINGS _ EVENTS ON THIS SITE!!!!
AS PARENTS CANT ACCESS OR MESSAGE ANYONE AND JUST BROWSE LET THEM REGISTER ON SECOND SITE - UNLESS THEY ARE REGISTERING ON SOMEONES BEHALF!
A great example:

look below and see services for weddings. Great layout!!!!
