Thanks for any advice.
Firstly, welcome to Webmasterworld.
On your single / multi page question, a single page will take longer to download, and its length may well put off potential susbscribers (especially as a single page form might give the false impression that ALL of the information is required). Of course, if all the info IS required that may be no bad thing, as it would act as a selector for those who really WANT your products / services
If you are more interested in building a larger list, then a multipage layout, with clear notices on what is required, and clearly marked "go to content HERE" links will likely perform better.
