Is Directory Plugin right for me?

I'm looking a creating a directory site that targets one individual niche. I was looking at the WP Directory and it looks promising, but I won't need all the categorizing.

I'd need to heavily customize the design/layout and information fields that businesses fill out.

Also, there's the thought of using wildcard sub-domains represent the specific city that the user is looking in.

Does the WP Directory sound like a good fit?
