Direct Homecare is selling home care and live-in care services for the elderly.
The website comprises of about 19,000 lines of custom and is using MySQL/jQuery/Ajax/custom CSS (no blueprint) and a few Yii extensions. Pretty much every feature of the Yii framework has been used 
The company is based in London, UK. Two friends had the idea to setup a website selling home care services for the elderly to help the rising demand for in home support from carers. More info about the company About Direct Homecare.
The site is still being actively developed and a new version will come soon.
