Even though you're offering websites for free, you really should show some examples of what you can do. Being that you posted this at a programming forum, many many users here have at least enough understanding of web development that they can make a basic website. And even if they don't, the overall user base here could figure it out quickly enough to make a halfway acceptable website.
I'm not trying to knock what you're doing, I love seeing people around here trying to give back to the community, especially when it's helping them learn at the same time. It would just help anyone who might be interested to see what you can do
[Edit]Also, if the right people request, they wouldn't even need you to host it for them. If you're doing this with web templates, don't expect anyone to want you to make them a website(literally anyone can use a template). If you're doing it with html/css/etc, then you can just give people the files that make up the website rather than a hosted website and a URL.
