Hi Zombie, I guess I don't understand your problem yet.
This is my idea:
1)Visit the forum and pick up a suitable category.
2) Under the category, create a new topic. Give a description about your business, and place your URL in a normal for mat: Like
http://xyzabc.com
3) URL filter will automatically convert it into a active URL.
4) Here is an example. Created by one of the v7n members.
http://givebestdeal.com/?q=node/438
5) If this is not what you are looking for, let me know. I am happier to implement what you want to see.
Thanks,
