At Group3 we do customization on many CMSs including niche content management systems.
One of our recent projects was for BrighterHome, a real estate company in North York, Ontario, serving Toronto & GTA. The customization was done on WebsiteBox, a niche CMS platform for real estate agents.

Group3 helped the client in focusing their efforts to choose the right niche market for their real estate agency. Then using content marketing and proper creative, Group3 created their website to be a well designed, targeted lead generation tool for their real estate business.
