I have a website designed that is a PSD file and I have a a custom template system that is in plain text. if you know HTML then you should easily understand how the templates work with any explanation. This is a multi-language website so it cannot be done with commercial site. I do not think that this is a real difficult task for those who know what they are doing.
I will provide you with a PSD file and the template layout that will need to be changed to accomidate things. These temaplate files are plain text files that combined to create the HTML.
Please contact me with any questions.
