Sorry for the slow reply...
In regard to a BANS WP Plugin, I dont think there is one available yet. The script does however allow you to mod a template system (Header & footer files) that can be incorporated into an existing WP site.
Like I said above... the MOST important thing with BANS is making it unique to what hundreds of others are already doing. Two sites for example that I use as an acid test...
www.racecars-forsale.com : Raw, default BANS. Averages 45-50 monthly visitors with little to no marketing. I have 5-6 inbound links from discussions like this. Total time to build site including setting up hosting, database, etc- 1 hour.
www.getaracecar.com : SAME eBay category, modified templates, added several SEO related sections and built out the menus in relation to what Word tracker told me people were looking for. 160-200 daily visitors, 450-500 daily page views, 30-35% clickthrough, 14% conversion.
Time to install: 1 hour, time to customize template, 6-8 hours, time to SEO optimize, 8-12 hours. In total about 2.5 days of time spread over a full week.
The above are two extremes. So how about:
www.carolinacloseout.com - optimized, 110-120 daily visitors, overall 14% conversion.
www.carolinacloseouts.com - non-optimized, 12-15 daily visitors, -1% conversion.
www.earnhardt88.com - 50% optimized, 4 hour build/launch time the rest comes over the first 30 days, hour here, hour there etc, site gets about 80-100 uniques each day converts 12-14%.
I have more... but its time for another cup of coffee!!
