91911 PHP form on demon (UK)

I am currently developing a site: [login to view URL] The form on this page doesn't currently work as the service provider (Demon in the UK) don't allow the 'Post' option to be turned on due to security issues. They have suggested looking at [login to view URL] to resolve the issue but we are not up-to-speed with PHP hence why I need some help in getting this form to work! Only interested in hearing from people who can prove that they can get the form to work. Form needs to be sent me initially until the site goes live. Any questions, please ask! There could be ongoing PHP work for successful programmers. I look forward to your bids.
