I could imagine writing a PHP-Script that runs on my site (rowi.net) asking for name, converting and output this file to the user. So you can override those convertings. BUT, I could also imagine that this isn't fair to greenflag.com and could be punished, am I right?
If not, I'm glad to provide this service if you are happy to use it.
By reading their copywrite notice here, it's pretty clear that you can't incorporate their website into annother one.
