Hi there,
if the work is really just about creating HTML+CSS templates, it will be a quick one. Of course, depending on the way you plan to use the templates, it might be a good idea to create a separate template part for a single product (like Iron Series or Minion Advanced), so that this part could be replicated in the body of the text. The templates will also need to have the markup necessary in order to inject the actual content into them. However, for this part I would need to either see some parts of the script injecting the data, or to consult with you the way the injection will be handled. Other than that, everything seems to be pretty straightforward.
Should you have any suggestions, comments, objections, just let me know.
Sam
