RE: Is there a way that the database will open up to a specific caterogory when someone lands on the page?
Yes, for example, this link will land you to the “Food Processing” category on your site:
To get the link, filter your directory by the chosen category and then copy the link from the browser’s address bar.
RE: Is there a way to limit how many cusotmers show up on the home page?
The cMap template already limits the entries per page to 20. If there is another value you wish to use, you can us the cMap Template Customizer to change it in the Pagination panel.
Hope this helps!
