Hi,
Based on the requirement of your relative, I think he should opt for designing of a website on content management system like Wordpress as it will not only facilitate him building a website at a cheaper cost but it will also give him the capability to manage his website from administrative panel without any technical knowledge. Additionally creating a website in wordpress using template is also cheap and he will not have to pay monthly cost. I have used a company in the past and you can discuss your concerns with them www.dhwajatechnology.com. I think Wordpress can serve your purpose to the maximum!
